Exactly what I do. Why should I deduce that the format, if it is a format, does not suit me? Why should I deduce that the format must be changed to suit me better? I can invent my own any time I want as can anyone else, and I track Wh. You can too, why don't you?push themselves to row about 10Km a day and have less than an hour a day to spare.
The math might be quite a challenge in itself. Once you have developed it, I'm sure there will be lots of subscribers; please don't fight over the rules, we've had enough of that recently.
But is the C2 challenge a format? I think not, so I think it's risible to call something a format when it's not a format and then complain that the format is wrong. Like complaining that the moon is made of the wrong type of cheese. Anyone can do anything they like, somewhat different from everyone being required to run a marathon.
It's certainly not a sporting event, there they have tracks, prizes, competitors, even judges, anti-doping, corruption, Olympic committees... Less is better, how lucky we are to be able to do without.
