It has 32° total timing, 8° initial 24° mechanical. At 60° total advance with vacuum, 60-32 total = 28° vacuum advance being added. At idle it was at 32° total with vacuum. 32° - 8° initial = 24° vacuum advance being added. So it is somehow adding 4° more vacuum advance while revving it in park at a lower vacuum signal.

And I'm seeing that everything says to fully seat it clockwise and back it out counter clockwise to reduce the timing at cruise. Mine was not having any effect though. Same exact timing whether it was fully seated or backed out 8 full turns.
