What is your worming program... 
We have our own farm, and about 30 acres. Dad keeps on top of the land, rolling and harrowing etc, and we only have 3 horses on all that land, so we just worm 1-2 times a year. Just when feel its necessary really. We've never had a problem with worms *touches wood*
As already pointed out above - interval dosing for worming horses is normally totally unecessary - especially in low risk situations i.e. adult horses, poo-picking, not overstocked - so the equest / equest pramox 4 doses a year regime is in my opinion total overkill and will eventually lead to the development of resistant worms.
Worm egg counts are usually done spring to autumn (forget tapeworm eggs here). I suggest (and we do) Junish, Augustish, Septemberish. If counts are above 400 eggs per gram we worm (annual rotation between panacur type, strongid-P type or ivermectin type). In winter (about december) we do either ivermectin & praziquantel (i.e. equimax)or moxidectin & praziquantel (Equest Pramox). As we are a low risk area for tapeworms we only do them once a year in winter - high risk areas (acid / peat soils) probably need to do 2 X yearly.
As a matter of interest - why do people still 'auto worm' instead of doing worm counts? Doesn't it cost more in the long run (as well as the resistance issues)?
