Actually in your example 1st points =(1000 / 10000) * 10 = 1 2nd points = (1000000 / 10000000000) * 100000 = 10
so no they wouldn't be higher rated. It's simply a fun way to attempt to grade overall *contribution* across projects. Agreed that it can give small projects more points still at least whilst they have a very small subset of users where that includes 1 or 2 powerhouse hitters but because of projects like MilkyWay and Aqua giving it ridiculous amounts of credits thereby basically making the current combined credits meaningless I think it's a better reflection of contribution right now at least in a leaderboard sense which is really the aim.
