What it does
Enter how many items a job has, how many are done and how many seconds it has run, to see the progress, the speed and an estimated finish time. The estimate assumes the speed stays constant.
It runs entirely in your browser: nothing you enter is uploaded.

FAQ
How is the ETA calculated?
Speed is completed items divided by elapsed seconds, and the time remaining is the items left divided by that speed. It is a straight-line estimate, so it is only as good as the assumption that the rate stays the same.
What are the limits?
All three fields must be filled in and non-zero. The finish time is a clock time without a date, so for jobs that run past midnight rely on the time remaining; if completed exceeds total, the remaining time shows "--".
