There are various types of progressions that are rarely mentioned. Not just the "named" ones that people have come up - we all know those. I'm talking about using a progression properly. For example - on a single 0 wheel - Let's say there is a progression on a straight up bet - if no win after 37 spins, we increase the unit size. Now this seems fine, we do have to recover from the loss of 37 units at this point and the only way to do so is to increase the bet size in order to both recover the loss and reach a profit. Now, let's assume we are playing 2 numbers - I'll make them #20 and #30 4 spins in, #20 appears and it's removed from play... and now we continue to play #30 until 37 spins have passed and it hasn't won. We are at -5 units and most people will increase the bet on #30 since it's been 37 spins without a win. This is where everyone thinks about progressions wrong. You have to look at the individual results within the cycle - and not the bankroll balance. #20 appeared on spin #4 and made 32 units profit. Therefore - there is no need whatsoever to increase (use a progression) on #30 until spin #69 - not at spin #37 when the first cycle is over. The win on one location "buys" extra spins to cover bets that haven't won yet. So is there still a need to win 1 in 37 ? Now for this session we only need #30 to appear once in 69 spins and we all know that it will appear 1 in 37 on average. So why increase the unit size by the rules of the progression at spin #37 when there are still 32 spins until it's needed ? This is why progressions are used improperly so many times. I'd call it a "perfect progression" when you are aware of your bankroll and know exactly when to step up a bet, NOT by your "rules" of the progression, but instead based on your balance. Below may sound confusing but bear with me. Let's assume a person were to play every number on the table, and remove the winner when it happens. We should also assume that the smart player can keep track of the results. Here is a complete cycle of spins, betting every number and removing the winner - and keeping track of only the profit made by the winners... So, our bankroll is at -88 units at this point. Because +437 units were made by the 22 numbers that DID appear.... and the 15 numbers that didn't appear caused a loss of -525 units. Now let's assume we are using this "perfect progression" - the cycle is over, we are -88 units.... we are in no way going to increase the bet size. Consider the "pot" of 437 units we have put away (virtually of course) Most gamblers have this "fault" in their thinking - they have played this system for these spins and are sitting at -88 units, "time for a progression to save the day !" Of course this doesn't work - it will tank, we all should know this. Most don't though. Let's instead think about our pot of profit - and how to reach a bankroll profit to end the game. We have to take our pot of 437 and subtract what is needed for a profit to occur, so 437 - 89 = 348 is now in out pot. 89 is needed to result in 1 unit profit since we are at -88. So, every spin from now on will have one of two results. A played number will win or A non-played number will appear, subtracting X from the pot. X is of course the total on the table being played ( 1 unit per played number ) the next spin is #22, our pot which is 348 the next is #1, the pot is 348 the next is #14, the pot is 348 the next is #36, 12 is taken away - the pot is 336 the next is #15, the pot is 336 the next is #26, 11 is taken away - the pot is 325 the next is #33, 11 is taken away -the pot is 314 the next is #1, 11 is taken away - the pot is 303 the next is #1, 11 is taken away - the pot is 292 the next is #9, 11 is taken away - the pot is 281 the next is #26, 11 is taken away - the pot is 270 the next is #26, 11 is taken away - the pot is 259 the next is #35, the pot is 259 the next is #33, 10 is taken away - the pot is 249 the next is #11, the pot is 249 the next is #5, 9 is taken away - the pot is 240 then 5, 9 is taken - the pot is 231 then 23, 9 is taken - the pot is 222 then 28, the pot is 222 then 29, 8 is taken - the pot is 214 then 31, 8 is taken - the pot is 206 then 25, the pot is 206 then 18, the pot is 206 then 35, 6 is taken - the pot is 200 then 22, 6 is taken - the pot is 194 then 20, 6 is taken - the pot is 188 then 35, 6 is taken - the pot is 182 then 10, 6 is taken - the pot is 176 then 5, 6 is taken - the pot is 170 then 31, 6 is taken - the pot is 164 then 25, 6 is taken - the pot is 158 then 31, 6 is taken - the pot is 152 then 13, 6 is taken - the pot is 146 then 6, 6 is taken - the pot is 140 then 6, 6 is taken - the pot is 134 then 14, 6 is taken - the pot is 128 then 16, 6 is taken - the pot is 122 then 7, 6 is taken - the pot is 116 then 32, 6 is taken - the pot is 110 then 30, the pot is 110 then 36, 5 is taken - the pot is 105 then 5, 5 is taken - the pot is 100 So we continue on...... 2,7,23,10,12,7,13,28,9 and our pot is 55 and on... 15,34 (win) and our pot is 50 22,36,4 (win) and our pot is 42 21 (win) and our pot is 42 31,11,9,10,22,14,4,7 (we're subtracting 2 now as there are only 2 left) our pot is 26 34,21,16,36,31,33,3,35 - our pot is 10 17,24,3,26,5 and our pot is 0 So in recap - this is 113 spins !! We are just now at the point of needing to increase bets in order to pull out with a profit. Doing so at the end of the first cycle would have been terrible, but instead (at this point) we are -85 in bankroll - almost exactly the same as what we started with at the end of the first cycle which was 78 spins ago. There was no need whatsoever to use a progression this entire time, because the early win in the first cycle bought enough spins to get us to this point without the need for any progression at all. This is something everyone should learn, instead of increasing bets when they aren't needed - increase only one the "pot" from the winners has depleted. Now only does it buy you much more playing time without the famous "keep throwing money at it until we win" ideology of most progressions. =================== Another way is to assume the bets on the table are winners.... and calculate that into the mix. It might be easier for some to see it this way instead of what was explained above - although it is the same thing exactly. So we have 2 numbers left at this point being played, I'll assume both are winners (+70) and we are at -85 units now. That means that we can't win and produce a profit. 2 units on each would be (+140) - so we can use this progression from now on..... Now at spin 127 our bankroll using 2 units per number is -141, it has to go to 3 units each (+210) The next spin one of the two appear and we are at -39 with 1 number to go. (remember the 37/38 people go into a casino thread....) Now, there is no need to bet 3 units on the last number is there ? 2 is fine. (+70) Spin 144 and it has to increase to 3 units again. Spin 156 it has to increase to 4 units. Spin 157 it wins and we're done....ending the session in profit. This produced a 1 unit profit for every 5 spins played on average with incredibly minimal risk. Losing bets were supported by the winners, at such a rate that NO progression was needed until much later in the session. Using progressions in this manner is the right (all be it harder) way to do it properly. Thanks for reading.
