That would just mean android avaliable projects would get very profitable for cpus and no one would participate in projects such as yafu or tngrid .

Would make a lot of sense to have 3 tiers of projects, though. 4x grc for the first (seti and WCG, probably) , normal for the 2 tier, and 3rd tier gets half the grc, to be used for projects that make redundant work.
