Hello everyone, I'm currently training with GTO wizard and there is one topic I'm really can't get my head around and come up with a concept that works in most situations.

--> Betsizing OTF, OTT, OTR in SRP and 3bet pots.

I created an excel sheet with all the different lines like shown below and tried to apply the concepts from different videos and establish the betsizes on different board runouts but as explained above, I don't have a concept yet which applies the correct bet sizings in 90%+ of the cases.
B-B-B (blank OTT, blank OTR)
B-B-B (blank OTT, draws arrive OTR)
B-B-B (draws arrive OTT, blank OTR)

Could you recommend some content that covers the concepts which apply or provide some context on how to approach this topic? I have obviously seen quite a few videos but I feel like I haven't seen a comprehensive overview but maybe that's just me.

Thanks for any help in advance.
