I'm doing some reading and found this:
In states where non-prescription potassium citrate is legal, the maximum allowable over-the-counter (OTC) dose for elemental potassium is regulated by the FDA to be no more than 100 mg (approximately 3% of the daily allowance).
That would explain the 99 mg dosage
Also found this:
potassium bicarbonate requires more dosing per day than potassium citrate. The dosing increases are due to potassium bicarbonate's propensity to be metabolized into bicarbonate in the liver.
This might explain the dose reduction from 800 mg potassium bicarb to 99 mg potassium cit
