I have been playing this for a few months with remarkable success.
How to choose numbers to bet?
Check current statistics of last 37 spins played. Pick a set of 7 consecutive numbers on wheel like 12,35,3,26,0,32,15, that won the least taken as a whole. For instance, if in the last 37 spins, only 3, 12,0 shown once and 15 came twice, you may opt to bet that set numbers only.

Which two numbers will be bet?
Only the latest two numbers if they did hit within last 37 spins, if only 1 did hit in the last 37 spins, only 1 number will be bet upon, if none did, none will be bet.

This betselection works on the principal that not all inside numbers come equally and in a perfect rotation. A few numbers will hit 4-5 times while another from your proposed bet numbers might not hit even once.

Benefits:
1. No betting on numbers not hitting for hundreds of times.
2. Takes advantage of any one or two of the numbers getting too hot.


downsides:
1. As any other bet, it will get all kinds of variances.
2. When all numbers remain active in your bet, you can miss some wins.


Progression:
 Increase bet once after 15 spins and no win and thereafter on every win.
Sooner or later, you will most likely get clustered wins and you move out having hundreds of winning chips.

Check this session. You can see that second dozen is hitting too low in the last 22 spins. Only two wins.
I get better cases than this. What could win it most?

"Up and Pull" as the name suggests has a limit set in advance of winning. As you suggested a 7 step progression where you keep a portion of winning and bet the rest. First of all my bet is not an EC bet but two dozens or like bets. Secondly, I am up for a very long and big win. Yesterday I got a dozen sleeper for about 19 times and after a win again for 9 times before a WLW came and end the streak.
 I want some progression that could exploit such cases fully. Anything else that could help winning better?

Mark,
      You are not getting my point. I have seen one dozen getting too bad for even 80-100 spins when it hits below even 1/4th. In such cases, I can close riding when I get WW or WLW of the leftover dozen/column but if before that  we have 18 wins followed by 1 loss then 8 wins followed by 1 loss, 5 wins followed by 1 loss and so on of my two dozens/columns, I could extract far bigger win and also can stop at a reasonable correction. As I said earlier, I have got access of table from 10 units to even 500k units. Which progression you know of that can do the best in the given cases?

Mark,
  Thanks for your inputs and the rider progression suggestion. My point is, when we play two most active dozens/columns or anything alike and it comes like 8 wins followed by 1 loss, then 11 wins followed by 1 loss and then 5 wins followed by 1 loss or anything alike, how to frame our positive progression to optimize the wins, specially when table limit allows bets from 10 units to 100k units?

Has anyone ever tried/read somewhere about reverse labouchere for two dozens/columns? I would appreciate if anyone can provide the link of that or explain the methodology(even in its crudest form). If it is nowhere, I would devise one myself.

Randomness is the core of betting or any form of gambling. If it is not purely random and predictable to a large extent the reward on the bet will be lesser. That is true with sports betting but casino gambling is purely random and chance to win is directly proportional to the risk involved.
        Randomness ensures that all silly money management ideas will fail eventually. Randomness makes all skills of choosing your bet go foolish finally.
          Randomness is not infinite though. It mellows usually around 6X of the break even point and crosses that very rarely. Although there is no absolute limit of randomness, it can go wild enough to kill a novice guy with irreversible loss. 

   In nutshell, no randomness, no gambling.

This omnipotent phenomenon of one dozen/column going laggard could be exploited to win huge betting rest of two dozens/columns which are pretty active with a parlay type safe progression, clever enough to handle some fluctuations. One can rather break the bank with this.
            Recently, in a session of mine, a dozen hit after 24 spins and missed another 9 spins before getting another hit. A simple progression player on a dozen could commit suicide getting such bad streak but I made one of the biggest win of my life with that.
              I am very much focussed on exploiting such things in an organized manner. I have got casinos with 10-500,000 units table limits online.Working on it to make it one of the most potent weapons against casinos. This thing did not work as well with EC bets and could take forever to win big, that way. Could be tried against smaller bets than a dozen, for sure.

It is already over $30k. Those who were skeptic of its growth have missed almost 90% growth when it was at $16,600 levels at 31st December 2022. It was near $20k in June 2022. Even from there, it is 50% up. This year we will see $50k levels for sure and a single fortnight can be sufficient to pull this much price. If it doesn't reach a new all time high by 2024, its bubble will bust forever.

As I expected and predicted, it broke the price barrier and getting costlier by more than $1k every day. No wonder it gets all time high before we thought it to reach there.

Any bet smaller than that could go even bad for longer. We have seen the fate of #3 in zumma book of roulette with 15k spins.

I have observed this for too long and hence sharing this with you. This is not backed by any statistical observation or upon any principal of probability but playing the weakest dozen ( a dozen which is hitting at 5/20 or even worse) looks very bad to me. That usually happens when 3-4 numbers of a dozen remains sleeper and rest of the numbers remain either average or below average. Even if a single number of that dozen is hot, it can not help much by itself.
        We all know that a single dozen could remain sleeper for even 40 spins and could reach hit rate of even 6/60, trying that is not wise. Maybe it helps someone playing safer.

There is a strong resistance against price growth of bitcoin at $25k. Once it crosses $30k mark, it will skyrocket. We might see an all time high price within a year and half max. If it doesn't work that way even upto 2024, it will lose its lustre and charm forever and could crash huge.

Remember we keep getting new goldmines and yet gold is getting costlier and scarcer due to its massive demand and value everybody wants to have a bit of it.if Bitcoin becomes a rare and precious asset with international acceptance, I see no reason for it going doomed.I m not so sure about other altcoins though.

With my variance management rules he could have won huge. Bankers and Players both do fine in the long run but people start playing martingale type suicidal idea that can win the least and lose the maximum. Strange to see such people in plenty still.
