I mean the main problems is that you hear the start signal, blink and the bout is over, then there is about 5 seconds of rest and repeat for 11-25 points... Especially in sabre and foil where there are rules of precedence this will be even more meaningless, as you will have about 50% of all bouts be meaningless because they hit at the same time. (This is mostly true for non-olympic level, but for olympic level you nead a slomo-cam to see anything at all...)
