Is the non-crunching projects due to not giving you any work, or due to set "no new work" (or suspended)? It's a significant difference here, since if continues to ask a project for work but don't get any, they'll likely with zero LTD, while other projects like WCG has negative LTD.

Atleast my experience with v6.6.xx is, any project is asked, starting with highest LTD-project, until got "Connect..." days cached, while the "Additional..." days is not filled-up with negative-LTD-projects except idle cpu...

So, if WCG has negative LTD, and "Connect..." is 0.1 days or something, you'll only have a few WCG-tasks on client any given time...

Not sure if CUDA-work is counted, but atleast for CPU-work and v6.6.36, all CPU-work is counted when it comes to assign more work. With resource-share also counted, a very low resource-share-project won't normally get anything, since it's seen likely you've got too much already cached to have any chance finish it before deadline...

So, if CUDA-work somehow also is counted into this (it shouldn't), if you've example got 6 days CUDA, 0.25 days with project-1, 0.25 days with project-2, 0.25 days with project-3, your last project WCG also will only get 0.25 days...
