If the best M1 score is attained at iteration N, then the best M2 score is always attained before N-th iteration.

If the best M1 score is attained at iteration N, then the best M2 score is always attained after N-th iteration.

If the best M1 score is attained at iteration N, then the best M2 score is always attained also at the iteration N.

There is no definite relation between the best iterations for M1 score and M2 score.
