I think this method works best if you want to build a bankroll as quickly as possible. If you have settled at a final limit, and you have e.g. 50 buy-ins, then you shouldn't move down at all.This looks like a complicated way to justify doing what you want to do (move up sooner). If you are looking at playing as a business, this method may work well. Most people will get bogged down in the math and the simpler "move up here, move down here" rules will be better for them.
As far as the math goes, it probably looks infinitely more complicated in that long text than it really is.
Take my current BR as an example. I have about $8,800 left, and I'm moving down to 200NL right away. The baseline for moving up is $9,000 ($8,800 + 1 BI), the baseline for moving down is $7,800 ($8,800 - 5 BI).
