No, the people who know roulette can't be beaten with any of the methods you have suggested because roulette is a negative expectation game. You ARE playing a neg EV game. This is a fact. The longer you continue to play roulette, the more likely it is that the house odds will overcome you.

Making sessions shorter doesn't make a difference. Changing your goals doesn't make a difference. If you are playing a neg EV game, you are likely to lose, simple as that. You guys really are fooling yourselves.
