Ok so I've been getting into some theoretical stuff of poker. And the question appeared in my head regarding range construction post flop.

My current thinking process looks like this: My OP cbet X% of the time so I must continue with Y% of my preflop range vs his bet sizing not to give him instant profit over me. And this is the same on turn and on river. Keeping my range as balanced as I can get it at my current understanding of poker.

Is this correct? If so how do I implement bet sizing into the the continuing range in that spot. Lets say my OP cbets 70% of the time using 70% pot bet sizing and how does that differ from 50% pot bet sizing?
