Alan, you and Anton made me wonder the reason for the fall spray.  After a little internet search, it refreshed my memory.  As I recall,  mites enter the bud scales in the fall, where they are protected from spray.  The idea is to get a good kill before that.   I suppose the spring spray is a cleanup.  That said, I might try just a spring spray and see what happens.

I wouldn't bother spraying trees when half defoliated.  The mites are unreachable with oil or poison once they enter the leaves so I think the best time to oil them is right before bud break- works for me.
