Adam T: @jpearman and/or @Dave Flowerday us Event Partners would actually love a primer on when matches could/should be rerun because they are likely a field fault. I understand your concern, but I’m not the right person for that - any official EP guidance on when to re-run matches should c…

@Dave Flowerday Thank you for your response. Here are some examples of simultaneous disconnects at the us open. 3 of these occurred in my matches, meaning that 30% of my matches were affected by simultaneous disconnects. I also suffered single disconnects but as those may have other causes I won’t …

Dave Flowerday: Now, despite what lots of people are reporting here, I have almost never seen both robots on an alliance fail at the same time. I don’t doubt it happens, but I just haven’t seen it much at all at my events. I don’t know if we’re just lucky or what. If it did clearly happen, and …

[image] sazrocks: Here are some examples of simultaneous disconnects at the us open. There’s no real way to determine much definitive from video. Plus, I don’t have time to review them all in detail. I will say in that first video though, you can see the LEDs on some of the controllers and t…

Dave Flowerday: I understand your concern, but I’m not the right person for that - any official EP guidance on when to re-run matches should come from the REC and/or VEX. It’s not my place to make recommendations on their behalf. … Dave, beside the James’ original analysis in the beginning …
