That's weird. With that fillfactor, you should have a very high
percentage of HOT update ratio. It could be a very special case that
we might be looking at. I think a self contained test case or a very
detail explanation of the exact usage is what we need to explain this
behavior. You may also try dropping non-critical indexes and test
again.

Btw, I haven't been able to reproduce this at my end. With the given
indexes and kind of updates, I get very high percentage of HOT
updates.

Thanks,
Pavan
