Hey there! We generally don't have that info at times, but the official twitter often posts the last Prize Fight scores to give you a rough idea of how much you'll need to do for the next one!
Yeah, because it is percentage based, there's no 'fixed' score for any level (60/30/10%)
The 'rule of thumb' is to review the previous PF (minimum) 10% results (posted weekly here) and aim for that score +2-5M more 'just in case'; there's too many variables to know the 'minimum' score for 10%. I guess it's safe to say the if you can do 90-100M every Diamond PF, then you're good for 10%. GL!
