I may be using it wrong, but it looks like the ETA isn't exactly updating itself properly. When running a process, the ETA starts out (in this example) around 20 seconds but then fluctuates around 30 and 15 and ends somewhere in there as well. It's as though the ETA is from that snapshot at that instant and not guessing how long the remaining time will take based on the speed of what's already happened.
