I don't get why you would 4bet AQo vs SB but not vs BB
I know right, those are both OOP 3Bets afterall 
This could be wrong but according to my observations of population tendencies, player pool's SB 3Bet vs EP is bigger than BB 3Bet vs EP.
So AQo has an equity edge vs SB 3Bet (that's why I call), but has no equity edge vs BB 3Bet (thats why it's a 4bet bluff)
AK I would just call always vs a 3bet.
Yeah I don't mind this option either to be honest, maybe one day I'll start mixing it up, there seems to be a lot of different opinions on this hand vs 3Bets 
With those ranges you are probably folding too much vs 3bets.
You're right, I'm gonna tweak it a bit, but not much tho, because global NL2 3Bet vs EP seems to be around 5% so I cant do much vs that kind of range anyway.
Any further thoughts would be much appreciated ♦
Thanks nitrol, I am aware of that thread (great one) but I kinda wanted to do my own version of ranges vs unknowns
