I don't know where to find total SP for all the rides of Jockeys, but by averaging the total prizemoney it gives an idea of the class of race won. The higher the class of races won by various jockeys would generally suggest better SP's overall I think.

It is easy to work out from both the above SR's the average odds we would need to make a profit. Following both [or any other jockies] on all rides would be a quick road to the poor house. Another thing with top jockeys is they tend to guarantee poor betting value almost every time... and that's another quick road to the poor house!
