Thanks for this option
, but as of now, it adjusts only the first place %, which throws the total finish % off balance (1st + 2nd + 3rd stops being 100%) and results in a lot of red colour. It's a minor issue because it essentially affects only rare top jackpots and doesn't alter the sims too much, but adjustment of the 2nd and 3rd place % would be great (if the 1st place freq is increased by x%, then decrease both the 2nd and 3rd place freq-s by (x/2)% or proportionally so that their total change is -x%.)
You could also make an option of filling the 2nd and 3rd place fields automatically, i.e. if the 1st place % is filled (x%), make the 2nd and 3rd place ones both equal to [(100-x)/2]%.
