Is this approach correct? If not how can it be improved
Download free metronome from google app store.
Make the setting vibrate with no sound and set it to vibrate once every second, 60 pbm.
Now search for a roulette wheel video on youtube, for example Bob Gordon Roulette Spins or Jafco or Mastersroulette or any other.
Instructions to predict when ball has around early or late 9 sec until drop, hitting deflector.
Estimate ball speed.
Each time you feel the metronome vibrate, watch what position that ball has on the ball track.
In the beginning you will see the ball at different place each time your metronome vibrate.
But during one moment you will see the ball in the same place during two vibrations.
In same place or very close to same place.
At this moment you will have early or late 9 seconds until ball drop into deflector.
Same for each and every spin.
You get 9 to 10 out of 10 predictions correct estimating ball speed that way.
This happens when you see ball in same place on the ball track during two vibrations.
Then ball goes from faster then 1 second to slower then 1 second, the breaking point.
What you do is that you read your reference number below reference deflector when ball has 9 second until drop.
See mastersroulette description about dominant drop zone.
This is superior method then LS crossover.
If they say No More Bets early you only change the time for the estimation process, for example 0.7 seconds.
Rotor you just watch number below deflector when ball is over and take two, three vibrations and see how many pockets rotor travel.
Start to predict and play with same rotor speeds.
