Can someone please explain the difference in desired reading for bench test as described in the manual (main and tail blades removed) and in flight?

I run the Analyzer on the bench with all blades removed and I get very good readings in all 3 axis. Out of curiosity in flight I take snapshot of each x and y axis and see result has extreme vibration over 100. Heli seems to fly ok. Small occasional tail wag 1-2 inch. Should I be worried? I still need to capture Z axis in flight.

My thoughts are that on bench test without blades it shows very little vibes so I think my heli mechanics is good. Only possibility left would be main or tail blades? They are perfectly balanced (i think).

Any clarification would be appreciated.

These are in flight captures...
