I kind of see what you may be doing but I likely don't know all of the details.
A card counter is aware of only 2 things - present running count and some sort of estimate of penetration. The data we agree on eliminates true count to find a strategy. The purpose of true count is to simplify a lot of data to a single value, although it may not be perfect. I have not given up on sticking with running count and avoiding true count, which wouldn't be perfect either.
Consider this solution for generic single deck insurance, no side counting.
let dR = decks remaining = (cards remaining)/52
let RCi = running count index
RCi = 52/36*dR - 1/18
if RCi turns out to be >0 and <1, round to 1
if RCi turns out to be >1 and <2, round to 2
etc.
if RCi=0 or RCi=1 then that is the index
if present RC>=RCi, buy insurance
I think the above approach yields the correct decision for all cards remaining except 1.
Instead of having to compute a true count, RCi is computed from decks remaining and constant values.
Just an idea. I can explain how I get the constant values. Also I think I can use this approach for RCi estimate when side counting aces.
