As he explain we bet on every winning number or DS, and reduce only if 6 DS should be covered. I have tried that, and must say it is not very good unless we get many repeaters, and in a row. We can fill four or five DS and making hits which pays less than the stakes.
On straight ups i think it is much better.
KAV! For corners it is a problem to say if it is a double hit if a number in the middle column hits, and it is hitted before in that corner, in the outer. It is not sure we can call it a double hit, as there are more than one way to say a number belongs to a specific corner.
I didn't say I bet on every winning number or the DS the number belongs to. I only bet on the DS's, with the understanding that when some DS's move ahead of the pack, you will be hitting them with more and more chips.
The only problem here is that you have to remember how many chips go on each active DS. Plus adding a chip on the last DS that won. So record keeping is very important.
You have to repeat all the bets on the DS's plus an additional chip on the DS that won last.
It's much easier on an air ball machine where you just hit rebet. On a live roulette you have to do it manually. I found that at some point you reach a profit, no matter how small it is.
Sometimes it happens fast, some other times it happens in a much longer run.
Whenever you reach a profit you restart. If all DS's are loaded you simplify as in the pictures.
That way you don't lose too much if the 0 hits. But if enough chips are on the DS's, a single chip on the 0 provides adequate insurance, and it doesn't affect the B/R in a significant way.
If you have to do the same on QUADS (corners) you have to determine how would you use the corners. If 5 hit you can either use corner 1-5 or 2-6. So you don't have to worry about 4-7 or 5-8.
This system works on streets too.
I assume it would work on single numbers, but when you come to the point where you bet many numbers, it will be difficult to keep track how many chips you put on each number.
Easy on an air ball roulette, very difficult in a live. Then it's a question if you have the time to place all bets on all numbers before NMB. For example you might have to put 5 chips on 32, 2 chips on 17, 4 chips on 1, 1 chip on 22 etc. etc. With single numbers most likely you will lose control.
That is y DS's or streets are a more manageable option.
