Odds and payouts are different things. If either the odds or payouts don't change, then the result is the same - eventual loss.
QuoteYou are so right there. Unless you dissect the game into simple parts irrespective of bet placement and odd, you are not going to understand game.
My sincere advice is if you need to device your own HG, there is no point in looking for going for the edge of variance as such a limit do not exist. You need to understand the cycles that happen in roulette primarily on numbers and you need to play a game that consists of multiple games. That will be time spent very constructive.
The fact is things do clutter. When they do clutter, repeaters do happen. When repeaters do happen the statistical relation between these finite cycles tend to lean towards and form a magical relation between two finite cycles.
However, if you see roulette as a game made up of a number of finite non-random events, it can help you constructing your sessions short. Short not in its literal sense of minutes or seconds or few spins, but short enough to avoid the game edge catching you forever.
