Without engaging with you, at least in baccarat (similar to the Black/Red comparison) in my experience really bad sessions/downturns/losing streaks, etc., are usually followed by 'better' presentments which are easier if you can hold your same frame-of-mind with your bet selections and recoup or at least come close to recouping. Moving/Playing past recouping and profiting is extremely difficult to capitalize on due to emotions, psych and financial concerns for most all players, again IMO.
Huge problem being, is the player's frame of mind and his ability to recognize the presentments and capitalize on them so close to the emotional and financial drain that just happened.
But as you said, there is, let us say, a good opportunity that will resurface after the bad patch subsides.
Again, in my experience I state the above.
