I'm currently planning the stats of my party members. However, because I hate fun, the party members in the game only go up to Level 20. RPG Maker VX Ace's stat-curve generator doesn't let you set the max level, however, only creating a curve from Level 1 to Level 99. This would just be awkward, except because it only goes up to 9999 at Level 99, I can't make a curve with the specific numbers I'd like.
There is very likely no way to alter RPG Maker VX Ace to conform to my game idea's idiotic design decisions, so is anyone familiar with any sort of programs, sites, or whatnots to generate curves that could be used for stats? It has to be able to handle four-digit numbers (for HP).
