My thesis is that in micro levels it is better to raise the same amount on any position.
The reason is that you opponents usually don’t see what are you doing and they don’t think something like… “Oh. He added 1 more BB to his raise.. hm.. He did it because he always add 1BB oop.. “ but “wow!… This is 5BBs raise… Queens, Kings, Aces!”. And then you get the blinds with your monster because there was no action, because of the 1 more BB.

I also have to add something here. If you are really tight UTG (I saw your stats… you are!) then the most of the times you have hand, you don’t care to play out of position. So you want action. Don’t confuse your fishy friends with 1 “mathematic” Big Blind.

Note:
Don’t measure your stack with pots. In your example, 11 and 15 pots is the same amount or money. That means in both situations you risk the exact same money. (This is a very useful way to describe stacks and pots but not in this case.)

Again…
1 BB before the flop it is a serious decision and you are right overall.
You can have a much more bigger pot on the turn and river. Its your decision, if you want that or not. I just have to say…

Don’t tap the aquarium !!!
