The Focus events this weekend had > 3000 riders and was unridable. Joined both events and the lag was ridiculous, real world time of 10 mins was showing as only 5 mins in game. The volcano circuit was hilarious, took the best part of 5 mins to get up the tiny ramp. In the end had to bail on both events.
If you struggle to support that many riders, cap the entry or have staggered start times.
Won’t be joining the third event, and wil avoid future events with that many riders.
