Matt. Thanks for trying to clear up my confusion, but it didn't work. I'm as confused by the maximum as before, if not more.
I studied your spreadsheet and it did not make any sense to me. A lot of what you just said was not included on the spreadsheet.
Since dosing amount is the same per kg for every weight, why don't you just tell us how many days we can take the 1/5 dose and still be under the maximum. Or build a chart which shows what our level has built up to. Does 1/5 of a dose equal the 400 ucg/kg you keep referring to?
If the half-life is 20, and I have read that it is, why do you believe you have several months (if you are at 1,600 ucg/kg) before you are down to zero?
Sorry that I don't follow your line of thinking. I didn't think my idea was out of the box; just adapted from another difficult to divide use.
