> There are currently a ton of conditionals checking for various problems, as well as a horribly confusing unbalanced decrement + increment, and in general the code is a nightmare to follow.
> To make it worse, besides being confusing it doesnt handle all cases: e.g. a negative position increment gap from the analyzer will just result in total chaos (corruption etc).
> I think an easier way to implement this is to init fieldinvertstate.position to -1, and for the logic to be:
> {code}
>   position += posincr;
>   check that position >= 0 && position >= lastPosition
>   lastPosition = position;
> {code}
