Chuck it is a three millimeter difference. I had the opportunity to check the optometrist measurements against my own which boosted my confidence in measuring. I measured my eldest daughter's distances too and she was 4mm out of summitry. Eccentric folks... :*) All Scottish decent on both sides. Must be the cold damp conditions.
My figures were formatted oddly, but that's not how I presented them to Zenni. They came to me formatted as 35/64 32/67 I presented them as: OD - 35 OS - 32 Distance - 67 Near - 64 Zenni did not appear to be confused about the formatting and reiterated the information just as I presented it. Coastal Contacts had no such trouble, but mentioned that they had a formula for calculating near focus instead of taking my number. I was curious about that, but I would think that accommodating a 3mm difference from centre would be far more important than any differences between their formula and my reality.
