My 2c about this situation...
At the end of the day rules are rules and the timings for this event have been public for well over a month. Even if you’re on the reserve list you should be ready as soon as the lobby opens (or close to it) rather than waiting until the scheduled race start to turn up and expect the race to restart because you can’t arrive on time.
I can’t speak for Pro but the Am race was delayed by nearly 10 mins anyway, the lobby had been open for nearly 30 mins before qualifying so why do you think that turning up 10 mins late and expecting a restart is acceptable? Everyone else was there in time...
Sure I’d have liked to race a full lobby rather than the 10 that finished but it is what it is.
