I'm in your corner lomaca.

Like you, I was just expressed my opinion based on the maths evidence I have seen over the years and 2+2=4 will always be correct to me too. If someone wants to believe otherwise, that's fine by me as long as I have the right to disagree, especially when basic maths is being replaced by 'belief'.

The only progression that can work mathematically is when you are winning at level stakes. Then you are financing the progression from the bookies capital not your own. I'm not going to argue that a progression can turn a level stakes loss into profit though by re-inventing the wheel [there is still a Flat Earth Society with a very large membership].
