Hey Dzapp, glad you are making progress with it!
If you've learned the PS1-6, however you want to label them, that's great. I coined the "6 postflop scenarios" to help break up postflop play into useful chunks. I know many people will find this change uncomfortable, but it is very logical.
The examples have the blind levels in the images, but what is being stressed is the postflop measurement of SPR. Preflop it is good to think in terms of big blinds or "M", but postflop you need to switch to SPR.
The initial chapters advocating larger raises with eg AA are based on achieving an SPR of 5 or less, so you can commit to nearly any flop. I do make clear that cash game players are rarely going to be able to achieve this low SPR even with aggressive 3bets, so in deep-stacked situations a traditional raise will be smarter.
Enjoy the rest of it and post again if you have any questions
