One 8 count of music only takes about 2.5-3 seconds so if we are talking about at least 1 and possibly 2 extra 8 counts it would definitely matter to me!! Every team I coach right now had to trim an 8 count of material because we couldn't fit everything we wanted to do into the routine... A full up, a standing one to full, a triple toe back, half of a cheer, a front to back tumbling pass, and a pyramid transition all only take an 8 count
Now I am NOT saying that the over time thing is a big deal, im sure it has been drastically exaggerated from 1-2 seconds up to 5 and that no one is breaking any rules, as may have been implied. I thought everyone was aware of the "grace period" and I will openly admit I have had plenty of teams compete with music that I knew was 2:31-2:32 because I knew it would be ok... I did want to make a point (although maybe slightly off topic) that an 8 count can be a big deal and all of my teams could really benefit from one more
