Your proposal is acceptable... but I am reading it that this change is only being made as a concession to the stat-lovers.
It would be even more useful if you could accept the old results AND make use of them for the SCIENCE aspect also. If you are only accepting the workunits to bump up a person's stats it is kind of meaningless. It would be better if you could continue to accept the "best" proteins submitted to add to the pool of "good candidates" for the analysis phase of the project.
Just my .02 pence.
Ni!
