So, I guess the lower the car count the better and since the Jeg's All-Star race is only three rounds, that should be a breeze compared to a normal six or seven round race.
There's a flaw in the D2 payout schedule (there is no 7th round loser, 7th round loser is called R/U in S/SS.) So, your chart should look like this, IMO:
NHRA Div. 2
3rd round loss = $125 (-$35 less than entry)
4th round loss = $150 (-$10 less than entry)
5th round loss = $200 (+$40 more than entry)
