It was 501w for 20 mins.
I dont know if someone has manually applied it (unlikely, as plenty of other ridiculous efforts in the Zgames events not been flagged) or if going over 500 for 20mins is an auto trigger.
Edit - Linking dodgy performances from this thread: DQ because of Watts or W/KG?
Its a 500w trigger for 20mins that sets it off. So feel free to do 499 for 20 & be fine.
