Moving to 24 concurrent wu's best time seems to be in the order of 52 seconds and offset stays longer but still fails and then the average is maybe 54 seconds or more

With 36 concurrent wu's the best time is probably 54 or 55 seconds average but 24 hours later the offset is generally maintained and the average runtime for a wu is still around 55 seconds.

I have just set for 40 concurrent and will try to report my findings

In each instance above my offset is approximately 35-40 seconds. The idea behind that was that for at least some of the running wu's there will not be wu's in cpu mode at both the middle and end phase at the same time.

Remember this is a 4 core non ht cpu running 100% all the time.

I believe that it may be possible when flooding the cpu like this to have settings that you can set and forget for maybe a week or more at a time. So far it is not perfect but looks promising. Does the answer lie in matching the cpu and gpu runtime for each wu perhaps?
OdChap do you mean that on your machine you crunch an HCC GPU WU in 52 seconds with 16 or more threads.
I am between 7 and 8 minutes with a 7970 GPU and a 990X CPU.
Have I missed something !!!!!
