Lets think about this. Of all the options the small blind has, limping is probably the worst in general. Agreed?
Folding shows that you have some level of hand selection. Min raising is pretty bad too. Raising 3x is the best in my opinion Raising 4x is good too Raising more than 5x in most situations is a poor play.
So 3x > 4x > 5x > Folding > Minraising > Limping
Eh... kinda. But then the ratios matter a lot. You cant categorize everything into "Raises" because 2x is way different than 3x. You dont want to categorize min-raising (2x) with limping, but its close.
