So I got bored waiting for my curry to arrive and did some Man Maths.
Using the below assumptions I've worked out which strategy is best with a refuling formula and a 100KG fuel limit.
- 100 second lap
- 60 lap race
- 0.03 seconds loss per lap per KG of fuel carried
- 1.666 KG used per lap
- 0.05 seconds loss per lap per lap of fuel carried (1.666KG)
- 30 second pit stop for fuel
Code:
Stops Strategy Total Time Diff from 0 Stops Rank
0 Stops 60 6091.5 0 3
1 Even Stop 30, 30 6076.5 -15 1
2 Even Stops 20, 20, 20 6091.5 0 3
3 Even Stops 15, 15, 15, 15 6114 22.5 6
1 Staggered Stop 40, 60 6081.5 -10 2
2 Staggered Stops 30, 15, 15 6095.25 3.75 5
So the fastest strategy is always 1 pit stop. So with the free choice of tyres just pick 2 sets that will cover half a race each and job done.
And the fact that the different tires have different rates of degradation at different tracks and the longer lasting tires are slower? You say 1 stop is fastest yet most likely you'd have to run tires that are 1-2 seconds slower over the entire race distance to make it, so what gain 15 seconds but lose 100+ via worse tires?
The whole point being that some cars can make a one stop, others can't. Then you have a car getting stuck in traffic and changing strategy on the fly potentially.
In 2008 the tires could last so long they frequently didn't change tires when coming in for fuel. Does that seem plausible with the tires we have currently or anything close to them?
People are just going this is what happened the last time we had refuelling so obviously it will be exactly the same. Did they have bulletproof tires in 2008, yup, do they now, nope, that will have a massive effect on both in race ability to keep up the pace and forcing changing tires at pit stops.
Will it work out well, I have no idea, it could be crap, it could be awesome. But presuming it will be identical to the last time their was refuelling is nothing short of ridiculous.
With tires today there is an absolute definitely faster strategy for every track... yet almost never do we see everyone on the same strategy. Some cars simply can't pull off a one stop at tracks that other teams can, some teams can't turn one tire on performance wise so will be better off throwing in a short stint and getting back on a faster tire.
Presuming that there being one obvious strategy for pitstops means every team will do the same is ridiculous. Back in 2008 that wasn't even true with multiple teams on different strategies and that was when tires were much less of a differentiating performance factor.
