I'm not sure why they call these "team challenges" Gridcoin is an account manager which offers financial incentive... hardly a "team"

I agree with you, Chooka.

This should be my last challenge with my beloved tahiti radeons, so I choose to run with AMD Users. Thanks to all participants. Except gridcoin, of course ;-)

Yeah I'd like to see Gridcoin separated from the stats a bit like ASIC vs NON ASIC. It's not a level playing field. Certainly not a "volunteer" group or team imo.

Mmm, bold idea. :-)
But, to be honest, they crunch the same WU like us. Maybe a "ghetto" is unfair.
I'm thinking at something like a "ban option": when someone start a challenge can exclude gridcoin or can let them partecipate.
Don't know if it's easy to do for developers.
