Introduce new mechanic to better handle longer tasks. Since smaller tasks will take only a little time, and longer one will drag, there is another calculation of remaining time based only of last 10 tasks times. That will filter out the small tasks and take into considerations only the longest ones that are finished. Also there is a logic that takes maximum of old way and a new way of calculating ETA to prevent regression when only small amount of tasks are finished.
Moreover I increase threshold for smallest remaining time from 1 minute to 15 minutes.
