That's right, in this case a reset is done. Because we set up the program for one dealer and get the results just by playing with one dealer. If there is a change, then the settings may not be suitable for playing with this dealer, or this dealer often throws out the same numbers.
If this happens during a bet, then a reset should be made. It is very risky to continue betting according to the old settings after changing the dealer. It is not known how much the generation of numbers will change, but it is better to start the game over. Reset and play the game again, or move to another table if this dealer often generates the same numbers, or you have an unstable result with this dealer.
It should be understood that in the event of the first difficulties, we never take risks. We just reset and start over, or change the roulette, if it's RNG, or the dealer or table, if it's Live.
The programs work well when the settings match the roulette generation algorithm, which is determined by the number of repetitions of numbers during 10-15 spins. The more repetitions, the less stable the game with SpinMagnit, but more confident with DoubleMagnit. In this way, both programs complement each other.
