You have just run bad. That happens, but as you get up the levels you will be having a lot better value with KK. Don't ya worry.
And YES, limp/shove on these levels is 99 % of the time AA+
I love that you put + after AA ♦ 
Well, everyone can say anying, I just have my own experiance, and according to it it's -EV if we both push preflop. Even if the sample size is small, mathematically it makes it more likely that it's -EV than it's +. I KNOW this sounds crazy, but still, the numbers indicate it.
Everyone says this is a stupid thing, but show me some facts! I thought this is absurd aswell BEFORE I filtered my hands and saw the actual results.♦
I dont care if you 4beted with KK and the guy folded, you would have had the same result with 72o. It doesnt matter if you have Kk there or not. I'm curious about the times the the guy DID call your shove, or shoved himself.
On higher limits it could be profitable, but on nl2-nl5 it doesnt seem like. If you disagree, feel free to back up your claim with something constructive than: lol.
IM NOT SAYING, and the results dont mean naturally that it's -EV to actually bet/bet/bet it preflop. Most of the times the villain calls it before going AI, so it's purely for value, and works of course. Clearly it's +EV to bet with KK as much as you like.
BUT if you actually get AI, it doesnt seem as strong.
