18117 - low PPD

I recently had a couple of work units go through my systems for project 18117, they produced roughly 60% of what I would normally expect my GPUs to produce.
I expect variance but not this much (projects 18116 and 18115 were a little low but not so much that it matters).

A quick search failed to turn up posts regarding the beta testing and/or release to FAH of this project (it didn't turn up any posts at all).

I did not see how my RTX 2070 Super reacted to the work unit.
I did see how my GTX 1080 Ti reacted, it seemed to be running at 94-96% GPU load but the clock speeds were high (like it was free-wheeling waiting to be loaded down).
I suspect with its low atom count (25K) this protein is not meant to be going through wide GPUs like my RTX 2070 Super and GTX 1080 Ti.

GTX 1080 Ti - https://apps.foldingathome.org/wu#proje ... e=46&gen=9
RTX 2070 Super - https://apps.foldingathome.org/wu#proje ... e=34&gen=2

For reference I would expect the following production from my cards:-
GTX 1080 Ti - 90-100K per hour.
RTX 2070 Super - 100-120K per hour.

Now that you mention it... On an RTX 3070 a 18117 job takes about 1.5h, and returns ~100k points. Usually, I'd expect at least 3.5M PPD, while 18117 only less than half that. It makes sense that on wider CPUs, PPD drops even more.

Could the owner of this project answer why it doesn't appear to have been beta tested and is being allowed to run on hardware it is clearly underutilising, even if it's just to acknowledge that you're going to do nothing about it.

If the only projects available at the time you need do download a new assignment don't happen fully utilize your hardware would you rather it be idle or inefficient? It's hard to find a single answer that will satisfy everybody.
