What are snowie_m  snowie_c   snowie  gnubg_m  gnubg_c   gnubg ?!

In match stats there's a "Equiv. Snowie error rate", so why not adding an
"Equiv. Snowie overall rating" based on the "Equiv. Snowie error rate"
(using same grouping as Snowie) ?

This would be Snowie-like without changing gnubg rating system ...
