Good observation on your part on the no-brakes format. Riders mostly over-brake when they start to add more/harder braking, and loose entry speed.
Your overall goal if good, nothing wrong there; the other steps that go in that direction are smaller bites one would take to achieving that.
As for braking and then realizing you could have gone faster...that's a not uncommon situation that occurs. Front brakes are the most powerful thing on the motorcycle, consider that a much smaller single rear brake can stop the engine. How about approaching the braking with the idea its a fine adjuster, capable of great force, but in the end, getting the entry speed correct for you (no too slow or too fast) is the key.
There are a few pieces to this, we can work on them for sure.
