I just checked, and your PB 2K is faster than the fastest current time for a lightweight 40-49 year old, and would have ranked in the 95th percentile for last year, which makes the 70 not-so-unbelievableGammmmo wrote:I'm not so sure about that calculator. Mine's coming out around ~70. Knowing that pro cyclists are 75-92ish (even 85+ is fairly unusual) I can categorically say I am ALOT further away from that sort of ability that the calc would suggest....
That said, it would make sense that the calculation would tend to be least accurate at the extremes -- for example, it estimates the VO2 max for the slowest (so far this year) heavyweight in my age category as 13, which I'm guessing if it were accurate would cause death.More info: https://en.wikipedia.org/wiki/VO2_max
