There's been a bit of talk recently about weight divisions in MMA and how they could be better. More evenly spaced so weight cutting is less of an issue and fighters "between" weight classes have an easier time picking a division. 10lbs seems to be standard for the weight divisions but as fighters get bigger 10lbs becomes less of an issue and then smaller heavyweights can end up fighting someone 40lbs heavier! Boxing has too many and MMA has too few, particularly in the mid-sized area. Currently it's Flyweight – 125lbs Bantamweight – 135lbs Featherweight – 145lbs Lightweight – 155lbs Welterweight – 170lbs Middleweight – 185lbs Light heavyweight – 205lbs Heavyweight – 265lbs Why not just go for a standard 8% difference? 125 to 135 is 8% more. 135 to 145 is 8%ish (a tad over but we can round down). Then (rounding down each time)... 156 168 181 195 210 226 244 Or in real terms 10lb twice, then 11lb, 12, 13, 14, 15, 16 and 17. Or just go with a standard 10lbs for each jump?
