I have seen versions of this many times in my life. Unfortunately, that progress report can hurt a lot, is something we devs often miss.

From my horror cabinet: 1. Running count * on all sqlite tables 4x per second to show sync progress.

2. Progress bounce animation eating 80% of cpu (windows phone bizarro silverlight)

3. Sending myself 800 emails in 10 minutes…

The rule is quite simple, we are just bad at it. Computer to human communication should run at human speed.
