With most cams you won't see much change unless you move it 3 to 4 degrees.One tooth can be a large move in degrees.If your going to move the cam do it correctly.Advancing moves the intake valve closser to the piston,retarding moves the exhaust closer to the piston.Don't guess at it.

I believe one cam tooth is something like 15 degrees, at least thats what I've heard and it seems to make sense

very close, 14.4 degrees (25 crank teeth / 360 degrees)or (50 cam teeth / 720 degrees)
