Knowing the Gemini has a static timing of about 8°
Depending on age of dizzy, mechanical advance of about 10° and much the same for VAC advance.

Thats a nice spreadsheet to visualise all the numbers. Im going to move this to tools, and sticky it. I think others doing conversions without a matching factory calibration will be able to use this to get a starting point.

Thanks to our friends at thirdgen.org for creating it!
