Sometimes, in a math problem, we can specify too many variables that we want to achieve, all simultaneously, but that are inconsistent with one another.

Your bankroll is your bankroll. If you want to grow it to a higher level in the shortest mean time, then you should bet full Kelly. Therefore, you should readjust your bet sizes as often as is practical. Now, having said this, you can't now stipulate that: a) you want a different ROR, b) you aren't going to adjust until you reach x percent of your original bank, or c) you want to systematically pull money out for expenses. All of those actions are inconsistent with growing your bank from A to B as fast as possible.

Do you understand the dilemma? You get to stipulate certain variables. If you stipulate too many, you no longer can "solve" your problem.
