Also on similar note: I believe that announced times of record attempts should be mandatorily respected. And if the record attempt fails, the number of the corrective repetitions, or the time frame available for them, should be also clearly defined. I find it strange that some athletes seem to have better conditions than others. Some of them seem to be lucky enough to be good friends with judges who are willing to supervise their trainings for several days, or allow over a dozen consequent attempts throughout a night, while at others the judges simply show up just immediately before the attempt, and disappear immediately afterwards, not letting any possibility for another attempt.
I know there are several top freedivers who use to train up to 10% (or more) beyond the announced performance during the record preparation. Apparently they do not have the luck to be good friends with judges who would be present there and ratify one of their succesfull relaxed training dives, so they have to put all on a single card during the offcial and stressull event with no right for an error.
I believe that the rules should include a clause that either no record attempt repetition is allowed, or if yes, then that the judges are obliged to stay, and it should also define how long exactly, and how many repetitons are allowed, so that we have same conditions for all.
Although I greatly respect the performances achieved in such "friendly" conditions, I do not find it is correct and just to those other competitors who may have less chance to have a good friend among AIDA judges, or have less financial means.
