Normal practice is to adjust the depth of cut to just over the thickness of
material, so the teeth & gullets just clear.

The theory is this gives a faster tip speed and a smoother cut.

Tip speed depends on radius, not on blade position. The sides of the
blade are just causing friction, not cutting, so a _slower_ speed would
have the advantage, And if you're rubbing on the sides of the sawblade
anyway, then stop it!
