Allen kid here. Yup, we went over the 8-minute time limit (by 3 seconds). Pretty crushing situation for us, especially the seniors who did not ever imagine region would be our last performance.
Apparently, there were some issues regarding the timekeeper with other bands as well, so it's getting appealed. If you watch the performance from first to last note, it's under 8 minutes by around 20 seconds, but it's hard to tell from the rules what exactly starts the clock. Nothing is super clear right now, but it's all in the hands of UIL at this point...we shall see.
