Default Goblin replacement pulley has 37 teeth?

Goblin 700 [H0101-S] has (1) extra tooth, 37 instead of 36.

It's no big deal, but I was just wondering... I haven't seen any feedback as to why the decision was made to add a tooth on the replacement tail drive pulley that SAB is sending to everyone.

SAB must have deemed it benificial to speed up the tail ever so slightly?

Anyone out there have the "official answer" for inquisitive minds?

Gives a little more tail authority. SAB took advantage of the recall to make the change for everyone.
