[EM] three tier approval

[Roy]

Your idea is very similar to Dyadic Approval, described in:
http://groups.yahoo.com/group/election-methods-list/message/7157

If I were to distill both ideas to their essence, it is to take CR 
scores and use them in the pairwise contest matrix, but with 
particular limitations on the allowable CR scores.

Has that particular idea been proposed? Would it ameliorate the 
strategy problems of CR?
