Have received a great new idea to allow the premature finish to any match period. This is useful in junior matches where period length can vary. This will be in the next version of NetScore, and you'll be able to do it by touching and holding the START button during a period. It will then give you the choice to continue with the period or to end it early.
This would be terrific. In our local comp, periods are often quite a bit shorter than they're supposed to be, and on a couple of occasions, I've had to mentally track the stats while waiting for the countdown to expire on the previous period so I could start entering them in the new one!
