I would agree with you that it's not the primary reason for PG to change the BA threshold.

The real issue is that BA work units are just no longer required or have projects lined up to use the unique capability.
That is possible, but unlikely, in the long term. Having a resource that will turn out results that rival supercomputer clusters, but at a lower cost, makes the BA capability, a valuable part of FAH. Perhaps THE most valuable part of FAH.

If you look at the total for Linux, and assume it is ALL BA:
You have 13 out of 17032 current TFLOPS.
You can't measure the value of BA folders, by just TFLOPS. Their value includes a much faster turn around speed, an ability to handle much larger work units, and a tolerance for the larger up/down loads those larger work units require.

The diligent silence, the refusal to address any substantive issue raised on this thread indicates that PG is not worried about the loss of those 13 TFLOPS.
You do remember that:
1) Stanford is closed for the holidays. There will be wok done on FAH, throughout this period, but it's not a full staff, as many will have scheduled vacation time, etc., during the shut down of the University.
2) Dr. Kasson just responded, above. PG has not hired their donor relations representative yet. Why make substantive changes now, when they're still lacking that asset, and need to study the issues?
3) One of the main issues is the current point disparity between what a BA rig earns folding BA wu's, and what the same rig's ppd is when folding regular SMP work units. That requires a careful adjustment.

If they(BA folders) are moved to smp, or if they ALL simply quit, the difference to PG is negligible.
I strongly disagree, because nearly every BA folder has other non-BA folding rigs, as well. BA may make up "only" 13 TFLOPS, but the rigs BA folders run, add a lot more to that figure.

This of course is very harsh news to those who invest and pay utility bills to run these WU.
The rising electric rates are bad news, but most folders will respond by turning off the smaller rigs, and leaving the BA rigs running as long as possible. They do the most for FAH (per rig), and they do the most for our points.
FAH must run with whatever hardware the donors have, today. Tomorrow, our hardware may be made obsolete by the newest computer hardware. (Imagine a Quantum Computer), and BA by new GPU's with thousands of cores, but FAH will have to make those changes after the new hardware becomes available, not before. FAH itself, may become obsolete, if a faster and more accurate method is found to study folding proteins, that doesn't use a distributed computing project model.
There are no guarantees here. Not for FAH, and not for folders either. Both FAH and it's donors, do what we can with what we have, today. For tomorrow, we need to stay flexible, and expect change - because change will surely be there.
