First of all, VO2 is not VO2 Max. That's like confusing your car's gas mileage with the capacity of the fuel tank.
Secondly, what is actually measured during a beep test is the number of cycles the athlete endures. From that, one can calculate an estimate of his VO2 Max, based on the average performance of athletes in the past, who apparently had their actual VO2 levels measured directly.
Why didn't you say this like 10 posts ago? Instead you have to go on with all the annoying passive aggressive sh*t that drowns out the main topic.
