I'm sure their fitness is good, but I don't think this is an indicator that they could hang with elite or pre-elite rowers for 2km. I bet the muscle fiber composition ratios will be statistically and significantly different...
3min is well into dominantly aerobic contributions. Fast twitch is for very short time periods.

Ostensibly, this would be a prognosticator created off of athletes whose training is based around the 2k event, so applying it to someone who is training with a different focus may have utterly different pace ratios.
Like saying a marathoner's 10k pace is XX% of their marathon pace.
Probably wouldn't hold true if you apply it to an 800 or 1500m runner.
That's certainly not what running does. Running has a very strong link between races at various distances.

What separates elite rowers, swimmers, cyclists, runners and skiiers from Crossfit type athletes is not physical conditioning. Its the specific discrete movements required to be successful on the water, road or snow. Most Olympic swimming events last less than 2min. But it takes hundreds of hours to develop the water feel to move effectively and efficiently. Same with rowing.
The erg is a much more brutal measure of physical capacity. It doesnt matter much how you do it. Just put force on the flywheel and you will get a good score. But try row like that in a boat and you will be slow. IMO its why the US men largely are not successful on the world stage. When everyone has big ergs they are no longer a discriminating factor. GB, NZL, GER can compete because they can row well AND pull big ergs. The US men seat races it self to mediocrity. On the other hand the US women have shown that when you raise the physical standard you can dominate for a while. Until those that row well raise their physical game.
