The new tablet scoring system is a big hit with most people. So much so that we have people volunteering to score. Often these people are children. Often these children are not treating this role with the respect it requires!!
We have evidence of playing/tinkering with scores and fouls during games, anybody can see this thanks to the play by play feature on the results website. The tablets are not toys.
The score-sheet/tablet is the official document that records the game, if a child makes a mistake while using it that mistake stands, not the scoreboard. For this reason the WBA has a bylaw that says all scorers must be at least 12 y.o.
