I just did some 2-ply analysis tests and I found that it even if you blunder enough for it not to pass the 1 ply filtering , it still forces an analysis at 1-ply.
It doesn't seem to carry this forward and force a 2-ply analysis.
So maybe this is a bug.

(Ian, do you have an example where GNU doesn't at least force a 1-ply analysis?)

If this fix is implemented then I see an issue where if like me, you set your filters to always accept 0.
then a forced 2 ply analysis of a blunder will have nothing to compare against.
I would suggest in this instance, the top play is also analysed at 2 ply overiding the filter.

Just to be clear here Ian, do you always want "your move" or "your move if it's an error that falls outside of the filtering" to be analysed at the top setting?

For "your move", then an "always accept 2" will produce this, for "your move if it's an error that falls outside of the filtering" then "always accept 2" together with the fix will produce this.


BTW not that I use it personally or see any point to it, "always accept 1" doesn't seem to work.
