Degreeing a Cam vs. Lining Up the Dots

OK maybe i have figured this out on my own

Intake opens 22.5 BTDC, int close 62.5 ATDC, rotates up to tdc and fires, ex opens at 62.5 BBDC and close 22.5 ATDC.

Over lap would be be 45 degrees.(22.5 before to 22.5 after tdc) sound about right for a small cam like that.

Them matching ## just through me off.
