I posted this in low stakes as well but I think more people here will be better versed in Odds Oracle :)

I am starting to construct a database and the first part of it involves writing pre-flop macro's. I
was wondering at what %age opening range does writing a macro become
important i.e. 60% pretty much gobbles up most hand types V will be
opening but just writing 2% weights V range to mainly AA and a few KK
combo's which will obviously affect post flop ranges drastically.

Hope someone can help :)
