My first 2 days on the grid, I completed 2 tasks a day. Then the 3rd day it took just over a day to do one. Then my 6th task started very slowly. I estimated it would take over 60 hours. I checked again when it was at 3% and then after half a day I checked again and discovered the Task Time was at 3 minutes with 0% completed. Arghh!! I ignored it overnight but checked just a few minutes ago. Task Time is just 3 hours but it is rated at 75% completed. No, I have no idea what happened during the night (no barking dogs, no points awarded) but I assume that this is all old hat to the moderators, who understand the mysteries of the Rosetta program. There are complexities here which do not yield to instant observation, grasshopper. But wait, and eventually all will be clear.
