Agreed, in a longer race pit strategy is important. Even in a short race, a decent bit of time can often be cribbed with speedy stops.
Many moons ago, we ran a Neo with a RB side exhaust. I remember a 15 minute final where we made one stop, surprised plenty of people and won the race.
This was partly because I had it screwed down pretty tight and partly because the tank was 3cc's oversize.
Anyway, what I was going to say was that a 20 minute final can easily be done, with three stops at 5 minute intervals.
Why?
Well, we start out with a full tank.
