Thanks for giving it some thought,
I stuck your values in my spreadsheet, See Attached,
Your values, like all values I've ever tried, cause all 4 code versions to
come out with the same answer at all input steps, using any set of fixed K
gains that I have tried.
As you sort of say, as l

A question to the math time-nuts
With the values of K1, K2 & K3 constant,
and the initial state of I#1, I#2 and Last_Input all zero
assuming there is no rounding, clipping or overflow in the math
and that if I've made any obvious dumb typo errors that they are corrected,
Given this PID type of
