A boulder final can turn into a horror show with the new 4 min rule

Imagine counting down the seconds in a boulder final and the athlete make a mega dyno to the final hold at 3.59, holds the big swing and the crowd goes wild. Few seconds later they might get even more adrenaline in the body as the referee says the boulder was not topped in a controlled way with both hands within 4 minutes. The IFSC rule says that the athlete, within the time limit, "Controlled the marked finishing hold of the Boulder with both hands." Another time dilemma might occur when the athlete reaches the last hold at 3.55 with one hand but touches only the top with both hands at 4.00. The control position occurs 4.01. Imagine the gold in Tokyo will be decided based on a judge subjective opinion in regards tenth of seconds. Probably this will not happen but IFSC must have this in mind, so IOC and the non-climbing spectators do not just shake their heads in 2020. Siked.nl has also published an analisis with a suggestion. There are many solutions and the most drastic one should be to start on two boulders at the same time which would reduce the time almost with 50 %. The solution for the referee problem above is to say that it is good enough to touch the top with one hand within the four minutes limit and then you can use as many seconds you want to control it.
