I mean like my distance might be only 1/8" from centerline, but someone else's might be 1/4"

Scribe the centerline, 1/4" or so from the edge of the hole, not scribe 1/4" from the centerline.  Then figure how far you want the edge of the tape from there.  You can scribe a mark there also.

Oval, so your thumb fits snug with no lateral movement.  If you want to squeeze, or want to use a ton of tape, or your pitches are off so you need a loose thumb hole, or if your thumb is round like a circle, go with a circle hole.

This is one of those aspects where there isn't a right or wrong answer.
 
I just concluded a 3 month experiment using milled ovals and oval slugs. I got in around 100 games in varying conditions. Sometimes they felt good, but other times awkward.
 
The biggest issue I had was with swelling. I didn't feel like I had the flexibility in adding/removing tape that I have with a round hole. In the end, I went back to my "customized" round hole (manually scraping out the sides) to get the feel I need. It's no longer perfectly round, but it's also not as oval as a real oval. 
 
Like most things in bowling, the only way to know is to experiment.
