This appears to be my exact logic.
I can imagine many places where you might be doing something wrong.
1. Are you sure you are scoring the final game correctly including
the proper accounting for komi?
2. Do you include passes in the random games? You should not.
3. Are you sure the eye rule isn't somehow broken?
How do you generate random moves for a game? A simple way, though not
the fastest is build a list of all possible moves, pick one at random
and play
it if it's legal. If it's not, throw the move out and pick randomly
from
the list again. You won't get random moves if you simply start at a
random
position but then just move forward in the list until you find a legal
move.
4. Do you use a decent random number generator? (probably not an
issue
unless you have a really crappy one.
