1) yama fought wnderweiss, aizen did near practically did nothing 2) i dont think yama is 5 times stronger than the other captains, making ichigo max power stronger than yama, there is no doubt in that, 2+2=4, 2.25+2.25=4.5, 2.5+2.5=5 what ever the exact amount of ichigos power with his hollow side he far outmatches yama, like i have stated he just cant use it, making him less skilled than yama but not weaker, and in a fight just 10% for example, is a great diference therefore with a very little diference in power you can "easily own" somebody as long as you know how to correctly apply your power, with just 20% diference you could probably "own" two fighters of that level and etc. so point 3)ichigo supposed to be around aizens level at this point (unohana said it in some manner, aizen also said he expected him to be much stronger than he wa showing, etc.)while aizen is also extremely close to yamas level (or at a par) means he is also close to yamas level
