Made some experiments with On Timer() and with the help of Terry Ritchie´s awesome tutorials it turned out quite graphical, so here are the results. Since there is no measured "update" based on passed time, you might want to adjust timer rates for your system. So far, program seems to function as expected but few questions remain. How much workload timers can actually carry? Is there technical limitations to expand use of timers, similarly that I´ve already used them?
Hope you have as much fun to play around with it, as I had writing it. More like a learning journey
