Terry, List,

In a reasonably well designed and operating damper system, assuming 
reasonably operating equates to appropriately regulated, I would 
expect not to notice when the damper levers pick up.

If I feel them pick up during key activation, that alerts me to 
something in the damper system needing potential consideration for 
some type of adjustment.
