There are many ways to bet but not all of them are equally effective, not now, neither on the long term. I'm going to present you a few and we could analyze them even further. Let's say I want to bet repeaters and win within 37 spins/36 bets (maximum). By betting each and every number which comes is not the optimal way because there will be times which the 1st repeat occurs late, personally I've witnessed to happen on 19th spin and from simulations on 23rd spin. That's why we need to come up with something better than this, my 2 propositions can be summarized on 3 words: double or half!! So my 1st idea is to increase the numbers which I'm betting just enough in order to win easier and faster. On the same time I won't increase the cost of the total bets, it will be decreased because per coup will be shorter in duration, the payout will be less but more frequent, thus approximately the same but with reduced cost. For each and every number which hits we'll bet it together with 1 more not shown number, I'm doing this by betting the splits of the numbers which are coming. For every repeater there will be also another number which hasn't hit till the moment we bet it, therefore hit to un-hit numbers goes 1 to 1 ratio by betting the splits which include the 1 hit numbers. There are 2 ways to end with a single win and restart from scratch, either 1 of the numbers repeats which is more probable with dealers rich in repeaters, or by the 1st hit from 1 of the other half numbers which is most likely with dealers rich in uniques. Whether will be 1 or the other we don't mind as long as both of the situations make us win. Calculate bets in order to coup with a single win. My second approach is a bit different as it bets only straight up numbers and only numbers with 1 hit in order to repeat. This time instead of doubling the numbers we bet we're going to half them! This is how, pick any half of the roulette wheel (18 to 19 pockets), when there is hit on your side, your half, bet that number, as a matter of fact bet every number that shows up but ONLY on your hemisphere (half wheel). Start from 1 and add till you win or 37/38 spins passed without a single repeat within your half. Personally I've never seen all repeaters fall only to 1 half of the wheel (any half). My 3rd way is different from previous 2, if any number can be disappeared for 600+ spins then for this extreme limit there the opposite, the shortest possible which is 2 hits in 2 spins in a row. If the longest limit is the ice then the shortest is the fire and as we well know what is hot as fire can never turn into ice immediately and vice versa. Therefore it makes sense to initiate a progression every time a number hits twice in 2 consecutive spins, I recommend BR for 148 to 185 progression steps. Yes, some numbers exceed this limit but those numbers didn't hit back to back on 2 successive spins. I'd like to here your opinions, suggestions, recommendations.
