@KLinardo: We had a dry qualifying this time, so the speed difference between your fastest lap in practice and your qualifying time should give a good estimate the effect of fuel load.
I’ve been assuming 15 seconds plus pit time for the cost of each pit stop - normally, pit time is whichever takes longer: tyres (10-15 s, random) or fuel (0.5 s/kg).
Hopefully that’s enough data to make an estimate and decide.
Does heavier fuel load increase tire wear? Is the weight on the tires dynamic as it takes the weight of fuel into account?
…I don’t know, actually. I’d expect that effect to have an effect in the tenths of seconds or less, though.
Oh I know, but where I’m usually at in the running order, tenths matter
I guess I see what you’re getting at. I feel like the errors in the other numbers in the calculation (particularly effect of tyre wear on lap times and pit entry+exit time) are going to add up to multiple seconds by the end of the race, though, so personally I’ve been ignoring anything like that.
(Actually, looking at the spreadsheet, you have a lot of rear tyre wear - have you ever gotten those rear tyres up past 20% wear? How much time were you losing per lap at that point?)

Worth to remember is the time in pits does not include accel and decel in pits I think (correct me if I’m wrong). I’ve found I usually lose about 20 seconds on a pit that takes 12-14sec. Really torn between one and two pitstops, but think I would lose too much time per lap, especially concidering I usually have the highest tirewear of the race 
No, that’s absolutely correct. A couple of us looked over the Snetterton race footage a few weeks ago to try to estimate the additional time - I got 14 seconds looking at lap times, and I think … Killrob? Someone in the IRC channel got a similar number looking at gaps before and after a pit stop.
The way I ended up doing my calculations, I was going from one stop with 33.6 kg to two stops with 20 kg each - so instead of 16.8 s in the pits plus about 15 s lost from pit-in and pit-out, I’d be looking at 20-30 s in the pits and about 30 s from pit-in and pit-out, which works out to a loss of 23 s on average relative to the one-stop strategy. Which, given how much time my car would be losing per lap above 20% tyre wear, I’ll more than make up in the 15-20 laps I spend on fresher tyres with a two-stop strategy.

I think I dropped a second per lap at my worst tire wear earlier. I don’t remember what track that was. I think I’m going to want to be on fresh tires due to the amount of driver errors I had in practice.
Summary of my season till now:
1st Race at Silverstone: rain, 1 random pit stop too much, no driver errors, 18th place. Ok.
2nd Race at Snetterton: dry, 3 driver errors in couple of minutes, 2nd place. Wow. Hyped.
3rd Race at Knockhill: Lasted 150 seconds before shot down. Knocked-out-hill. Driver dead.
4th Race at Oulton Park: Lasted 5 and 1/2 laps before driver killed himself. Estimated finishing position 4/5th place. Employing.

This reminds me…How many people have actually been killed in this season so far? Pretty sure there were tons on the second race. The FIA would not be happy with this!
There should be an “In memoriam of…” segment on the last race’s live stream. 
just wait for a bit, there are more to come, let’s do it on the end of the season shall we.
with roughly about 15 to 20 twenty knockouts and about 5 the crashes killing the drivers, maybe between 15 to 20 drivers dead so far 
but it’s the 60s, more than a decade more before people actually starts to implement some sufficient safety 
But how much damage has to occur for a driver to be killed?
Good question. 60s safety was pretty rubbish as it was, so I think the only way to decide would be some complicated maths involving the damage received and the safety rating of the car.
I’m willing to wager no one walks away from a 200+ damage crash in BRC 1966.
Hello all!
There may be no race today but never fear! Packbat and I have a small automation fix for you all today.
Part 3 of the BRC Car reviews!
Glad to see you found time!

Is it still too late to send in a car for review? I thought I had, but the forum apparently ate my PM.
We’re going through the initial set of cars before reviewing the ones sent in after we started - I have your car, RocketplaneRacing, so hopefully we should be getting to it in a few episodes.
Yea. There are a few cars in my inbox that have yet to be reviewed. On the bright side its spring break week and unlike most college students I did not go to Panama Beech (that will be after the semester is over).
