Oval chain rings and chain wrap

Does anyone think you need to factor in running oval chain rings when calculating chain wrap and derauiler capacity? Part of me thinks yes as the oval adds two teeth at it's widest point, part of me thinks ignore as it's dynamic (literally 1/4 of a pedal stroke) and it averages to the same wrap as a round ring.

Thoughts?
