I don't understand the being easy on the refs. They could simply change their SOP to using two hand signals with two flashes of numbers. 6 fingers first flash then 8 fingers second flash, 68. Zero first then 7 second, 07. It would take a whole one second more. No big deal. I can't believe that simplifying things for the refs is an excuse when it would literally mean one extra second of finger flashes to convey fouls to the scorekeeper.
