Hope no objections Cross 2 minutes to do but an age to explain.
Have not tested but should be correct.
Modified your examples box so it now reports penetration for those ranges & all 4 warhead sizes.

You just enter Max Pen & Range but range must be in metres.
If you want to tidy up feel free.

On Dons note slightly out no bad thing it gives as good an idea as the gunner would probably have vs a known vehicle.
As I said handy at start so you know can penetrate at XXX rather than testing in a combat situation.
