To use FFZ you need,
To clock rotor or at least 1.2 of rotor rotation.
Let’s say it takes 3 sec.
Then you need to clock ball at least 2 rotations
So let’s add 2 sec and total is 5 sec.
If the ball as an indicator is used it takes about 0 to 0.7 sec to get prediction.
So we need ~6 sec to get FFZ to predict.
Alternative option.
Since you believe spins are close to constant in time to use timer as FFZ has built in.
Adjust it to let’s say 2 sec.
Then clock rotor with it.
One spin in 2 sec. rotor makes 18 pockets you observe results.
Next spin rotor in 2 sec makes 20 pockets it is 2 pockets more in reference time of 2 sec.
It means 1 pocket more in one sec.
If your spins are 15 sec long it means you need to add 15 pockets to prediction of previous spin.
In other words for each extra pocket to add 7.5 pockets to prediction.
Because reference time 1.5 sec is only short that is why we have so much to add for each pocket of difference. When all is moving and timer starting and ending it is easy to be wrong by 1-2 pockets.
Adjusting timer to 4 sec and observing rotor change in that time would be more accurate for earlier predictions where the ball still has significant amount of time to travel.
When we use roulette computer we are better off.
Especially with FFZ or FFV.
We clock rotor, it may be 4 sec, so even if we are by one pocket wrong in clocking the error is smaller. If we use half rotor clocking then it would be same but RC is still better.
Because the time for rotor starts after we finished clocking so total ball traveling time is a bit less.
FFZ is even better then
talking roulette computers because rotor calculation is based on remaining time form moment we finish clocking the ball. Another advantage is that computers designed as FFZ can clock rotor at any position, so player doesn’t waste time with waiting for rotor to come to particular position.
But everything has limits
