10-10 is technically available for a genuinely even round, and judges are strongly discouraged from using it. Judges are scoring in real time, with three minutes of information and about fifteen seconds to commit it to a card. A unanimous decision means all three judges scored it for the same fighter. A majority draw is two judges scoring a draw and one picking a winner. Compare your card against the official one, round by round, and look at where you diverged rather than just the final result.
