The average time between being issued a wu and reporting the result back to the scheduling-server.

Will be used in future to schedule WUs to be given to same type of machines...

For example, now WU might be given to one user who has their settings at "Contact server every 1 days", and the same WU might be given to a user who has "connect every 8 days".

The 1 day user returns his WU and it sits on Seti servers for 7 days till the other machine reports.

When prioritizing is enabled, WU will attempt to give to users with identical turnaround times on same day, so results come back on approximately the same day.

Another prioritization is that servers will attempt to give WUs with 2 results and some timout failure/download failure to faster turnaround machines, so the 2 results don't sit there for, say, an 8 day person turnaround.

Side benefits. Faster credit granting all around, since results will return around same day from all users, and 2 result + error WUs will be given to quick turnaround, and then granted credit...when returned (quickly).

It eventually could go even further than that! It will get into your L2 cache size, the amount of ram you have on your machine, there are several other ideas on how to specialize the distributing of work units, processor, machine type, etc.
EVERYTHING though in its own time!
