langue - Welcome to WCG and to the forum!

There are introductory posts in the forum which might help you, but here is my own experience.

Remaining time is only an estimate. The work units (WUs) for some WCG projects are extremely difficult to estimate accurately. The system also needs time to learn how fast your machine is. It is possible that a WU will take much longer than the initial estimate and so the remaining time may seem to stop decreasing, or even start to increase. Provided that the "Progress" field continues to move forward there is no problem. However, be aware that the WUs for some project may sit for several minutes at certain points without the progress appearing to move.

Also note that, if you restart your machine, the numbers may take a while to settle back to normal, depending on the project.

If you are new, the system will also send out your WU to at least one other machine (we talk about "wingmen" in the forum) to help to validate your result. For some projects this is always done because of the nature of the science, for others this will cease once your machine is known to be reliable. On the results page of the web site you can click on the WU name and see the wingmen. In the very unlikely event that you have been sent a badly behaved WU then you should see that the wingmen are having problems too. Eventually the system will stop sending out copies of that WU and the techs will be alerted to take a look at it.

I suggest that you let it run. Without knowing the project and details of your machine it is difficult to know how long might be "normal", but I have had WUs take up to 60 hours on a slow machine. The normal range is anything up to 18 hours.

I hope this has been of some help. Please persevere -- everyone is helping to get the science done.
