can estimated time remaining pause while waiting for user input?

Binary package hint: update-manager

The estimated time progress bar in Ubuntu is fantastic. However I think this qualifies as a 'wishlist' improvement, and may be related to bug #48733.
I am upgrading from 9.10 to 10.04 beta. I was AFK for several hours after initiating it, and a dialog was asking me to confirm pam startup services. When I returned and confirmed the dialog box, I was told the estimated time remaining is about a day and a half. Over the next 20 minutes this time gradually fell to a more realistic several hours.

I don't know how the algorithm is calculated, but could an adjustment could be made to pause it when waiting for user or external action?
