Reverse Labouchère

The more I think about it, the more I reckon it was 500 francs. This makes sense because his original line was 4 3 2 1 which means initial bets of 5 francs which was probably the table minimum bet on the outside chances.

I also seem to remember he had lines like 220 240  but he couldn't cash in because 460 would not be greater than 500. So they had to bet once more, which lead to them risking losing their fragile line worth 460.

500 is good for a table minimum of 5 as it allows doubling 7 times, typical for a bigger casino.

Yes it makes sense.

A lower table limit does limit the potential gains i.e. the potential recovery.

In the simulations I ran, with 500-spin blocks, 21% did reach a maximum betting of 500.
