I've also just read that another cause is because only one side of the
blade (the inside) is against the wheels. The outside of the blade
never rubs against anything - that can make the inward set teeth wear
differently from the outward set teeth.

I read 'blade drift' to mean the blade was not cutting where it was
pointed at. This can be caused by a crooked or bent bade, a blade with
too much pressure on the rear bearing, too little blade tension, or the
workpiece is not flat or warped, the cut closes as it is cut, any number
of things besides the fence. If you cannot hold the piece against and
follow the fence, t is not a blade problem
