Was Magnussen’s Canadian GP evaluation right after early heroics?

From 14th on the grid, Magnussen discovered the intense moist tyre notably potent within the first six laps when the circuit was at its most slippery, and carved his means as much as fourth by the top of lap three.

That put him in touching distance of the highest three however, because the circuit started to dry out, the crossover level between intermediates and wets started to shut in.

In measuring Magnussen’s early excursions versus these of Oscar Piastri, whom the Dane had handed for fourth, that crossover level arrived on lap six: Magnussen set a 1m34.673s, Piastri a 1m33.060s, which prompted Haas to carry Magnussen in on the next lap for intermediates.

So, one would possibly assume that it was the correct name for Magnussen to come back in – he’d now began lapping slower than the automobiles forward. A sluggish pitstop relatively harm his probabilities and value him monitor place, however he shook out in thirteenth nonetheless to not less than make a place.

“It was wanting good,” he defined post-race. “We took the correct selection on the complete wets – however then I feel we pitted off onto the inter too early as a result of we ended up having to take one other inter. We might have stretched that full moist, to then go on to the inter and keep on it as a substitute.

“On prime of that, we had a really sluggish pit cease. It felt like we had some alternative there – however did not get something out of it.

“We did not try to take any loopy gamble or something. We simply did what we felt was proper for the circumstances. And it seemed okay, so I feel we did the correct factor there to start with however – then did not again it up with the correct selections thereafter.”

Haas tried to go longer with Nico Hulkenberg‘s stint, and the German held on till lap 12 having made his personal ascent up the sphere to seventh. After the sixth-lap cross-over, Hulkenberg was lapping between 1-1.5 seconds slower than Daniel Ricciardo behind, earlier than the Australian ultimately took again management of eighth on lap 11.

However Hulkenberg was battling a automotive he famous was “not totally wholesome”, so it stands to motive that Magnussen may need been in a position to have gained a number of tenths over his team-mate’s vary of instances within the 1m34s. It appeared like Haas had timed its Magnussen cease to restrict the injury of the time taken to pit whereas the sphere unfold was ample, however the sluggish cease price about 5 to 6 seconds and the timing meant that Magnussen wanted to cease once more underneath the security automotive.

It was anticipated that rain was due earlier than the race’s mid-point, though answering Magnussen’s suggestion might be made with the advantage of hindsight. Maybe hanging it out till lap 15 would have negated the necessity for an additional cease underneath the security automotive for brand spanking new inters, that call-in ultimately shuffling Magnussen down again to 14th.

Let’s check out how the moist tyre technique might have performed out, with out that seventh-lap cease, and we’ll do the identical for Hulkenberg and his lap 12 pitstop – though his lap instances would require much less in the best way of extrapolation.

On the finish of lap six, Magnussen was 4.76s away from Piastri. Assuming he might proceed on the identical tempo, Piastri would have wanted two or three extra laps to mount a cross on pure tempo, though the necessity to again off onto the moist components of the circuit may need hindered that barely.

Regardless, Magnussen was not likely racing the McLaren driver; that is purely an experiment to find out if Haas might have managed factors. Thus, evaluating the laps of Ricciardo, Lance Stroll, Charles Leclerc, and Yuki Tsunoda is maybe extra worthwhile as some extent of reference.

Here is what we’ll do: ‘tare’ Magnussen on the finish of the second lap, and work out the relative gaps of these automobiles who battled for factors on the decrease finish of the highest 10. Subsequent, his recorded lap time from lap seven might be deleted and the delta over his earlier lap extrapolated to the top of the lap. He was roughly 0.36s up earlier than the braking zone for Turns 13/14, so we’ll take that off his sixth-lap 1m34.673s.

For ease, we’ll transpose in Hulkenberg’s lap instances from lap eight to lap 11; though he was over a second slower per lap than Magnussen, this was as a consequence of him spending longer in visitors. By the point Hulkenberg had acquired as much as seventh he was extra constantly within the 1m34s after the battling Fernando Alonso and Lewis Hamilton pulled clear, which is rather more consultant of the moist tyre tempo, though his calculated twelfth lap is far slower given his bizarre method to the hairpin.

We’ll apply that to his personal instances however, for Magnussen, we’ll as a substitute extra steadily degrade his instances in keeping with the drying monitor efficiency. It is arduous to know what the efficiency deltas per lap might be, as Pirelli doesn’t so readily provide that info, however estimating is half the enjoyable.

Here is the place we’re once we construct up the lap time image with conservative estimates for laps 12-15. (All figures in seconds)

STOP 79.594 44.124 46.644 49.181 50.751 93.551

Primarily based on the lap deltas, Magnussen seems to fall 10 seconds behind Ricciardo which places him thirteenth earlier than his cease – precisely the place he ended up after his pitstop. Hulkenberg is an extra 14 seconds behind his personal team-mate, though this good points him one place and places him 18th – marginally forward of Zhou Guanyu. That is all pre-pitstop nevertheless and, assuming a 25-second cease, each Haas drivers would find yourself a way adrift on the again – Magnussen is 79.594s off the lead, with Hulkenberg 93.551s away.

Recent intermediates for 10 laps would reward them with some lap time, though their real-world tempo on recent inters was not a lot faster total than that of Logan Sargeant‘s. And, if the plan is to save lots of tyres to make sure they’re in first rate nick for the second downpour, it is arduous to see it altering. So, assuming tempo is stagnant, the gaps will stay the identical.

Nevertheless, that is the important thing bit: how a lot do they get again from not stopping underneath the lap 25 security automotive?

Three drivers stayed out on the identical set of inters throughout the security automotive: Tsunoda, Valtteri Bottas, and Esteban Ocon. Collating a mean of their lap 25 instances, we get a ‘keep out’ lap of a 1m52.613s, over 10s faster versus the pit-in time that the Haas drivers really managed (2m09.198 for Magnussen, 2m03.974 for Hulkenberg).

However that 10 seconds is not sufficient to carry the Haas duo again into play – an end-of-lap 15 cease seems to be too late. The 2 principally lose a pitstop by staying on the wets for longer because the intermediates are a number of seconds per lap faster, and they’d want to achieve that again plus change for staying out.

What about stopping on lap 12 and staying out underneath the security automotive?

After his precise cease, Hulkenberg emerged onto the monitor in nineteenth place. The lap earlier than the security automotive, he was 9 seconds behind Bottas who didn’t cease. Assuming the identical hole, albeit one which was compressing as the security automotive began to again up the sphere, Hulkenberg might at finest have hoped to take a seat sixteenth because the stops shook out, nonetheless behind Bottas who finally didn’t register any factors.

It may need labored out for Magnussen, nevertheless; an end-of-lap-12 cease would have put him someplace between the Saubers, though recent intermediates may need acquired him forward of Bottas and knocking on the door of Gasly. That places him in Ocon territory when the stops come, providing a shot at ninth or tenth when the race shakes out into its last order.

Maybe, then, Magnussen has some extent – actually and figuratively. Had his stint on the intense moist been prolonged by 5 laps and never hindered by sluggish pitstops, he’d have possible introduced a way more compelling prospect so as to add to Haas’ factors tally for the season.

However, to cite Italian movie star chef and TV persona Gino D’Acampo: if his grandmother had wheels, she’d be a motorbike. Extrapolating from incomplete knowledge, particularly in a moist race, is commonly folly – however Haas may need been higher served to maintain Magnussen on the wets for a number of extra laps…
