SRP, IP 38% range, OOP 33% range.

Sizings 1/3 and 3/4

In flops A96, A95, A86, A75, A73, A65, etc want cbet 50% frequency and choose 1/3 sizin, why choose 1/3 sizing if want cbet polarize 50%?
This also happens on flops K65, K64, K63, K54, K53 ..., want check like 40%-50% and cbet 1/3

How you build range here against someone who not fold too much? and what sizing?
