So you are playing numbers in order, you are covering 24 and from that 24 twelve numbers you play double. You have 12 (13) pockets which you do not cover.
And you would like VB to help you to avoid some spins where the ball most likely is going to stop at 12 pockets you do not play.
Well it is not so simple I will try to explain it however my answer may disappoint you. As I explained earlier when you cover 24 numbers based on the graph above you may play 12 with positive advantage (pick point A) and 12 without advantage (numbers around A, so your total advantage couldn't be high if any.
Pick point A can produce 100% advantage if fully optimised.
The graph shows only possible advantage created based on ball distribution jumps (scatter).
If we combine with it our accuracy of prediction where the ball will hit rotor then 100% advantage gets reduced, but also the pick point would be wider.
Something as this;

Here we have 3 graphs.
The red one shows accuracy of our prediction (hits -prediction to rotor). The white graph is scatter or average ball jump on roulette wheel (a typical example). On the red graph the ball is hitting rotor about 10 pockets from prediction. From white graph we can see that from there the ball most likely jumps 12 pockets.
Blue graph shows possible final results where if we play 22 pockets we would have advantage marked with green area and it averages to about 20%.
Here you can see, advantage is reduced, but pick point is wider, if we play positions 20 to 25 we may have 20 % advantage. Wider we play our advantage reduces more. But you can see on blue graph, the green area which gives us some kind of advantage is wider; we can say from 15 to 32, it is 17 pockets. If you play 17 pockets you can see that on the edges you do not lose but also not winning or the advantage is small, if you play 24 pockets then 7 units would be full losers. So even in this case there is no point of covering 24 pockets. You would be better of covering 17 and remaining 7 add on top.
But even 17 is not very good, if you reduce it to 12 each covered pocket would have better returns. If you cover only one pocket, return will be the best, but now we coming to your point of covering wide sector so there is no huge deviation in win /lose. When you put it all together in this particular scenario the best would be to play 5 and the most 12 pockets.
Further more, based on your number coverings 24 pockets from 20 to number 6 (EU wheel clock way), if VB prediction points number zero , you are right in middle. But what if it is number 2. Would you cancel your play or not?
The ball has a higher chance to stop on numbers from zero to 2 and on the other side from number 2 to number 13.
27 and 13 are not in played sector, and you have huge amounts of pockets from 20 to zero which you covered but the ball has smaller chance to stop there. So you really playing only 10 pockets with advantage and 14 without. It doesn't look good and it tells us that in such case you should play your numbers but centered around number 2.
But lets say you waiting and play only if VB tells you 0 or 26 or 32 so the prediction is in center of your played sector.
It is better but something that you want to achieve is really not achieved. When you are winning you winning slowly, and when bad strikes on remaining 12 pockets comes you lose more. You think that with VB you avoided bad strike. And yes you did, but by how much? 10 or 20 % . It is same as from wheel we remove 4 red pockets and say now is harder to get 5 times black in a row. It is but the change how much harder it is doesn't help us much, 5 bad blacks will happen, a bit more distanced on long run but it will still happen.
So if progression is used you did not achieved anything. If you play flat bets probably you may slowly win something (hardly), but then again it comes to optimizing your play.
Redacting covered sector to less then 12 pockets and in such case your approach loses meaning.
Anyway interesting point/ thanks
