Thinking about that it's probabley why they run so good . Most Stihls have exhaust numbers between 96 and 101 with about 22-26 degree after opening of the transfers  depending .

Then too it depends on how accurately  you use the degree wheel because you can be off a few degrees one way or the other .It's relative  any way depending on the port size and predicted RPMs .
