lol I had 0 too. Thats honestly true. Different reasons though I never considered the results may not be fair. I did it because it is easier to follow where it is on the wheel and you can tell quicker if you won or lost. I know it makes no difference in practice and actually the wheel spinning is just graphics and nothing else but I still did it for that reason.
Sometimes I would cover 29/32 split with a saver on Green when doing similar strategy but want to double the chance of hitting at least something. Im not sure why now. It became habit but originally I think I once saw my Brother in a Casino do it and hit a huge win and it just seemed a "lucky" thing to do so stuck.
Its been a long time since I have done either of those now.
