If I understand how this works correctly, you should not be calling populate after every add an overlay. You should do it once you've added them all. I think what's happening is that you add the first OverlayItem and call populate() so it adds that to the ItemizedOverlay. Then you add a second OverlayItem to the list and call populate() and it adds those two overlays to the ItemizedOverlay resulting in three items in the overlay. So I think you're getting way more than the 20-50 that you think.
