How do Compubox numbers work in Boxing?

So I’m watching the Roy Jones - Tarver fight last night (which Tarver obviously won). And after the fourth or so round they show the compubox numbers. I believe Tarver won that round but the HBO cheerleaders were looking for anything to put Jones ahead on. And after all my years of watching Boxing I start thinking how the heck did they figure out those totals. Now there weren’t that many punches thrown per person in this round (about 50). But I’ve seen fights were there were more than 200 per round.
Is there actually some sort of compubox computer sitting around ringside counting up the punches with some sort of sensor or are there guys ringside hired to count all the punches as accurately as possible?

This has always bugged me so I’d really like to know the answer.

Both, sort of. There’s guys ringside pushing buttons on the Compubox computers, and the computer just stores and tracks all the punches

3 compubox scorers, each with two buttons for each fighter- one for jab, and one for power punch. If two of three hit the same button in the same second (or 1/2 second, I forget which), compubox scores a landed jab/punch for the appropriate boxer.

A separate set of guys counts all punches thrown in basically the same way, and the computer does the rest.

Like eman77, I’ve wondered about this matter, too.

Okay, so we have these people counting and recording ounches.

But they have no inputs to the judges, right? Although boxing is, perhaps, a cut above professional rasslin’, all too often, the boxing judges base their win-lose decisions on a reality, other than punch count.

So why do they bother with these counters?
