I don't recall seeing green top dressed with out being aerified as much as I see it here in The Villages. It seems that they top dress a lot to cover up bare spots.
Aerifying reduces compaction which allows water and nutrients to get to the roots. It also prevents the roots from being squashed. But removing compacted soil and organic material and replacing it with sand more space is created below the surface. Top dressing without aerifying only adds material. One the sand is absorbed, it may smooth the surface a bit but I don't understand how it helps the plants.
IMHO, green fees should be reduced when greens are aerified, top dressed or there are temporary greens.
