I hesitated to take credit for the idea as I wasn't sure if I was the first person to suggest this. Also, I began writing this yesterday ;)

I think I addressed your concern in part (e). I agree it's very complicated, but I don't think it's beyond the community to arrive at a reasonable and equitable way of devising standardized benchmarks. I brought this up to stimulate conversation - maybe others already have some ideas.

I'm not sure that the magnitude tiers solution you mentioned adequately addresses problems 1 and 3, and I think it closely mirrors the thread @donkeykong9000 wrote yesterday that I mentioned in regards to problem 2. I guess problems 4 and 5 aren't incentive related problems, but I still think they're worth keeping in mind.
