Our district uses 25 minutes for half and 30 for homecoming, only. The max time for a band's UIL Contest show is 10 minutes. This allows 5 minutes for bands to enter and exit the field, at the half (in a 25 minute break). Unless something beyond the band's control is taking place, I don't see why they would cause a delay to the start of the second half.
same in our district.
