Biased turblock results

I noticed that I sometimes win the first 5-10 turnblocks in a given turn. Other times, my opponent wins the first 5-10 turnblocks. In some of the longer casual games I've played, the priority seems to shift from me to my opponent randomly. Each turn, however seems biased towards one side: either I win all the TBs or he does.

I also get the impression that the more commands I issue (in some casual games with GW, I can make 100s of moves), the less chance I have of succeeding in getting TB priority.

Just to be clear, I know how to prioritize my moves and have a pretty good idea of how TB probability is calculated (50% units, 1st move vs. 1st move = 50% chance).


EDIT: I changed the description of the bug to avoid confusion with TB "lucky streaks" occuring over multiple subsequent turns. This bug had to do with multiple TB wins within the same turn.

Turn block is working well. If you want to provide an empirical analysis to confirm your impression I can unlock this thread.
