If alternatively you zero side to side at your 23y parallax distance you cannot get any parallax error at this distance so will be setting your windage exactly with no error, then every other distance will be zero'd for windage assuming a perfectly central head position.

It's also no use winding the parallax setting on adjustable scopes to 30y to zero side to side as the ret could move when shifting parallax.

I've seen no end of shooters trying to figure why they are missing side to side at 15mm targets around their parallax distance as no matter where their head is positioned they are going to miss the crosshairs side to side.
Thanks for the above Pete. Never even thought about setting windage at px distance, then setting elevation separately at zero distance.
