What's the largest streak of player or banker runs you've personally seen at a baccarat table?

Never said I gambled this way... simply just asking a question.

If you were forced to play baccarat but only needed to win 1 time in 12 tries (and then you could stop), what MM would you use and why? Not asking what strategy you would use.. just MM. (Assuming you're playing in a B&M casino with table limits)

The only additional rule is:

You must come out with at least double of your first betting unit.
