There's too many variables to be able to tell without actually doing it. Get out somewhere & fling some arrows.
That being said, you can get a rough idea if you can also shoot 3-under and play with your anchor (face walking). So, for example, if you shoot 3-under with a middle finger anchor and have a POD at 30 yards, moving to an index-finger anchor will adjust your point of impact by about 8". For me, this extends my POD by about 5-7 yards at closer ranges. Move to split finger and you gain another 5-7 yards. Moving to a chin (Olympic style) anchor gets me more than 7 yards extra but I haven't really played around with it much. It's probably a 50-yard+ POD.
Not really sure what you're looking to accomplish, though. Just scratching a curiosity itch?
