I'm curious why my progress percentages are going down. When I came home for lunch my progress was at 85% then when I got home this evening it was at 50% then just in the few minutes I've been here it dropped to 49%

Anybody know why?

Could you be more specific, please. What progress percentages are you talking about?

on my tasks window showing the progress of the task.

Yes and what project does that task belong to? What is the exact application name on that task?

I am betting you are seeing relatively rapid turnover of active tasks, possibly switching between multiple projects.

Open your BOINC Manager, and on the View tab choose "Advanced View" if not already there. Select the "Tasks" tab if not already there. Then toggle to "Show active tasks" if not already there.

Click on the "Progress" column header to sort by percent progress. Unless you have a very old computer, there will be more than one task active. Depending on your options the tasks will either be Suspended or Running. If Suspended, temporarily change your options so they stay running long enough to watch the increasing progress for each task.

Let us know if any one of your tasks in the list is clearly running backwards

Edit: PS Multiple tasks will progress at different rates, with tasks assigned to a GPU progressing the fastest.
