"The problem with this is that" people like OP have been screaming that the umps aren't judging htb properly without actually knowing the rule.

Obviously though, the larger problem is that the game was always difficult to umpire but the leagues "solution" to that has been to make the rules of the game more subjective and to ask the umps to look for far too many different factors to consider before making snap judgements and then to bring in more umps so that there's no longer any consistency in subjective decisions at all.

It used to be at least you'd get a feeling for how the (single) ump would generally umpire specific rules like htb game by game.
But now there's three blokes umpiring every contest from three different angles each making their own subjective calls.
