starting sector: 2
6th Rev Sector: 2
Outcome Sector: 4
It also means
starting sector: 1
6th Rev Sector: 1
Outcome Sector: 3
Other words stat and check after 6 rotations if it is same , it creates opposite result.
If from start until the ball makes 6 rotations is in same sector then most likely for that time rotor made 1 or 2 rotations.
Why instead of dividing wheel in 4 parts you just do not look number at start and after 6 rotations, because stating 32 and ending 17 may be in same sector but 25 and 34 may not be even they are more close to each other.
Also you do not have to start always when dealer spins you can apply same process at any time.
So let’s say one spin you start at zero, after 6 rotations you have zero again and the ball stops on 5 (opposite)
let’s say you start at zero, after 6 rotations you have 21.
It means that you started 1 or 2 rotations later (ball is slower). So 6 rotations is made in longer time therefore, rotor which moves in opposite direction passed zero and made additional 5 pockets to number 21.
So your real reference number is not zero, and it is not 21, most likely it will be around 28.
If using right amount of rotations in usual 5-6 depends of wheel, you can just geometrically project created angle to the other side from your starting point. That would bring you close to reference number.
But the problem could be that change in between starting number and ending number may be created by different rotor speed.
So for example you start same as in first example, ball is with same speed, but the rotor is faster. So you get 0 and 21. Now that 21 is created because of faster rotor and transferring angle would make it worst because created change (by rotor) needs to be adjusted in different direction.
When we put it all together if we play that way we do not know if the change is done by ball or by rotor so the best is just to look if numbers are close, if yes then play, then observe rotor speed. If rotor is faster add more pockets in ball direction.
And of course never ever apply it if the wheel doesn’t have strong dominant drop zone.
By my opinion there is no need for waiting 6 rotations and reading number.
Even if it is same as I explained earlier it could be overlapping different rotor or ball speeds. If it has difference it is useless, since you still do not know how the difference is created and what to do with it. If it is created by slightly slower ball or by slightly faster rotor, or both.
Focusing on something that is not productive is not really great idea.
You would achieve same or even better if you focus hardly on rotor to define how much faster /slower it goes so you can make better adjustments, and just use first number as an reference. Or if you feel that spin is a bit faster compared to previous spins, just wait few rotations until becomes similar.
I do not say this is great way of play I just believe it is better then what you did.
Often to someone inexperienced rotor may look as same speed.
But if you time it and find it 1 pocket per sec faster, if your spin is 15 sec long it creates 15 pockets difference until the ball drops.
