My best $ made in parachuting and I do lots of it, was close to 100k in one hr I had people joining left and right. I'm very good my record is 221 wins 10 losses. I mostly do it now to get faster and faster times. It's too bad the social club does not update your new fastest times. But yes for RP the best ones are the highest ones with 250 point plus checkpoint finishes. The longest jump is Over The Globe, 360 checkpoint points ( if u get 15 points on each one) highest RP depends on level, and the money can be decent if u get people to join and bet.
I'm going to start doing road races eventually, been polishing up my driving, I went 38 miles so far with out crashing.
