More action and more rest in semi format needed

During the start and the end of the semifinal there is only one climber on the wall, which means a lot of waiting and less action for the spectators. It would be easy to let the first four start at the same time on the first four boulders and then we could have two more groups before the first four moves to their next respective boulder. This would mean that instead of giving the athletes 12 minutes of rest in between trying about 30 times on four boulders, they would have 8 * 3 minutes rest. An advantage for longer rest is that the competitors do not have to be so strategical saving energy during their four minutes sessions and it will be more a Bouldering challenge than an endurance one. Power will be more important! Such format would also make it possible to increase the semifinal to Top-24 and to shorten its duration to 96 minutes instead of 104 minutes for Top-20. Do you think we need more action and more rest for the athletes?
