A healthy engine has all of its spark plugs firing properly, "on all cylinders".
A healthy roulette wheel is the same way, firing approximately 24-25 uniques every cycle of 37 spins.
When this fails to happen, the wheel is in a dangerous state with larger portions than statistically expected go missing; i.e. we get worse than statistically expected results (variance).
Being able to read these wheel states can be helpful at certain times like above where we see that our bet selection (which was the number 16) hit on this turn (76) and did so outside of expectation (58 spins since last hit).
We can see that it is fortunate that our number hit when it did because in the last 37 spins we have transitioned from a healthy state into an unhealthy one where there is a very oppresssive 16 repeats every 37 spins. This is the perfect oppotunity to reset this session and leave a wheel that is more likely than statistically expected to sleep our number selection.
Its when we blindly push forward without realizing the state of the wheel that increases our chances of getting nailed by variance.
At least by tracking the health of the wheel, there are times where we can make an informed decision & consciously choose whether to bet under the wheel conditions or not.
