A problem is you have a huge gap between expert and EXPERT. a person newly promoted to expert is racing against people who have been racing for years and are stupid fast. Let's pick on you, your fastest lap in ULWGP was 1:53, Jay ran a 1:46 that's huge you placed 9th. In D you ran a 1:47, Whitten ran a 1:44 again, huge. There's nothing you can do with traditional contingency to get someone to want to be an expert. You can be a fast novice in a year or two and collect, I don't recall any people who promoted to expert and were collecting contingency off the bat. Contingency, historically, is given to people who place well, and that's not easy to do when a new expert is going against people who have been racing at that level for years or decades. I know it's not easy when trying to determine how to pay out money but there's no real answer, Dirk Anderson and 212 Decals took good a stab at it by paying out randomly to the expert class they sponsored, so the only requirement was be an expert and race.
