Cam sync trigger tooth, EMU Black

According to the log,cam sync trigger tooth 69-70 - fluctuating at high rpm.

I then changed the secondary trigger from rising to falling which seems like solved my problem.

Now, it stays firm at 62, does it mean that I previously I had my timing retarded by 8 degrees?

I checked with strobe both with rising and falling trigger edge and it was right on the spot, same settings just the trigger edge changed.

Correct me if I am wrong.
