How full is my oil pan?

I know on a trans pan, the static level is about 1/4 inch above the pan rail where it will seep out the dipstick if allowed. Oil pans should be easy to figure out, just put the dipstick in and youll get a rough estimate where the static fluid line is. Used to be a good indicator of whether your trans dipstick O-ring was bad was if it leaked over night but not while idling.
I put seven of the eight quarts in and just an eighth of a quart in the filter and it was just below one quart low on a normal dipstick. So, it seems if I put another quart of oil in it would be right up to the normal level with a regular oil pan? And I'm not even sure if it makes it up to the seals with 5 quarts in a normal pan?
A couple other comments talking about keeping the oil lower. I normally just put 7 quarts in the 8 quart milodon oil pan.
But if I put another quart of oil in and it brings it up to the normal oil height I'm not sure if that theory is correct? I certainly don't know.
