Hi,

On your 'First', the v7 clients are designed to do block processing, meaning they'll do a period of one project [WCG is an ''umbrella project' seen by BOINC as 1], then the next, then the next. Assuming you have not changed the default resource shares [aka project weight], default 100, with WCG+SETI, that means over the longer haul, both will get approximately 50% of the FLOPS [An arbitrary way of measure through the Recent Earned Credit]. As soon as you start micromanaging tasks, BOINC get's confused, where's it's 'learning' cycle is about 14 days. Make a change and it will take another 14 days to even out.

BOINC scheduling work based on the FIFO principle. With 2-3 days buffer there's a good chance you're already interfering with that principle, particularly if 'repair' tasks arrive that have a deadline that is smaller than 2 times buffer [3 days deadline divided by 2 is 1.5 days, meaning they might get rushed]. Then mostly FIFO is dropped and Earliest Deadline First kicks in. I will not argue over the voodoo in that process... I just 'know' and accept and keep my hands off and hold my buffers at a level that is lower than half of the shortest deadline work. Mostly processing with v7 is then FIFO.
