hmm i do not understand where the problem understanding why it's wrong to 
have two same/similar programs comes from... to continue David's example:

assume MFoG and GNU can beat every other program out there 100% of the 
time.
assume MFoG can beat each GNU version 70% of the time.
let's have 2 GNU's and one MFoG play in a tournament.

what is MFoG's chance of winning? 70? nope, it has come down to 50%. 3 
copies of GNU's and its down to 35%. and all that time MFoG is clearly 
best - 70% winning chance or better against every other opponent.

what would make it fair is if MFoG could enter as many copies as GNU-based 
folks can.

(i am assuming with those calculations that the GNU version that gets 
lucky against MFoG beats other GNU-s, so the real numbers are not as bad 
(assuming different GNU's can't arrange the wins between them, but that is 
a totally different topic))
