@chambers, that's why we kept a paper running total on a separate sheet and had them sign that. Also for each dual there is a place to enter the name of the official, so my guess would be that if you have him enter his name that would count as well.
@CoachJoyce Doing multiple matches simultaneously is possible with multiple iPads. So us for example, we have 5 total iPads. I bought one and two other coaches each own one and the school provided us with two. So if JV and varsity go separate places we will send 3 iPads to one location and 2 to the other. So then when you upload them (as long as they are all on the same event) it all uploads together. So we could potentially film several mats at one time and then when you upload film from the iPad, it consolidates it under the same event.
As a side note, if you happen to miss a match or have technical difficulties and keep score on paper, you can later put the stats into MatBoss, you just won't have the video of it.
