I am using nightbot on my twitch streams, and I have 5 or 6 timers.
Set to come in at min 5 lines and 20 mins apart. However, all the timers execute one after the other, 3 at a time. So once the conditions are met, timer one executes, then about 10 seconds later timer 2, and then timer 3. Sometimes ther eis a break of a couple of mins then timer 4 executes, timer 5 within 30 seconds and timer 6 within 30 seconds.
I have past stream VODs that can show this too.
