Unfortunately, for the sake of the project and the way it is iterative, projects really want a quick result to determine what to do next. Each unit informs the next unit what it should ask. That's why there are sometimes very short deadlines.

As an interesting note on how complex it gets with WU's, I had searched and found a thread on a specific WU that gave me a crazy high PPD return. During Beta testing, several testers reported PPD return was low. I assume they adjusted the WU specifics to give it a more "fair" point return. But for whatever reason, the specifics of my onboard graphics, small atom count, number of steps, complexity, etc... I got a PPD nearing double my average. Most of the Beta testers have much more powerful GPU's and they reported lower PPD returns when testing. And it was also a Core 21 project, and most people state 20% or so lower PPD expectations. So every WU probably has a range of hardware that runs it great, some just ok, some struggle, etc.

Like P13877 to a GTX 980 with a preferred deadline of 1day.
It's basically not possible to return the WU in time for part time folders
> p13877. HFM Benchmark Data. These wu actually ran well on linux 970s (hosts F67/68) at TPF 4.5 minutes (0.3 days to complete). The 980 should be slightly faster than the 970 and able to easily meet the 1 day timeout.
