Engineers...You Have To Cut Us Some Slack...
We can learn the theory out of books, but you really don't know if it works until you try it.
By the way, Clem, on an 8" diameter damper, an inch of circumference at the OD is about 14 deg of rotation (1/16" = approximately one degree). That means that your recommendation of about one inch either side of TDC would be about 28 degrees between the CW and CCW stops. I don't have any toolmaker's dividers in my tool box, but you could probably trial-and-error the mid-point with a flexible scale.
