Why?
What protocol did you test VO2max with? Did you run? Walk? Bike? Pole walk? Ski? Swim? What kind of test design did you use? Did you increase speed? Grade? Resistance? How long was each load? What device did you use to measure gasses? Was it portable? Old? Brand new? Is it accurate? Was it calibrated correctly? Do you have other information from the tests? Lactate? Heart rate? Rate of perceived exertion? Was it a "good day" for a test?
The information obtained from a VO2max test is often useful, but the information needs to be looked at with a careful eye and with some perspective, because VO2max cannot tell you the whole story on whether or not an individual can perform. It is only one piece of the puzzle that all of the above questions can affect.
"Performance" in terms of the endurance sport, is a puzzle with a lot of different parts. Some days the puzzle pieces fit together, some days they do not. Sometimes, the puzzle pieces are rearranged and change shape. Tough conditions? High-pressure race? Challenging course profile? Technique not working? A high VO2max may be your friend, but without other pieces of the puzzle, you may just be out of luck.
O2 consumption is not everything. Research these days suggests that neuromuscular factors (i.e. strength and muscle activation) also play a significant role in "performance". With the higher speeds and more challenging course profiles used in e.g. Nordic skiing competitions, you also need to have muscles that work efficiently. If your muscles do not work, will your lungs alone get you to the finish line?
A highly economical athlete can beat out one with a higher VO2max. An athlete that knows how to use the right technique in the right place can have the edge on his/her competition - sprints can be won by 0.01 seconds, so transitions and tactics can make the difference between 1st and last. Skis matter - at a high level, there are not as many differences between competitors, at lower levels, there is a larger difference between a ski with the right fit and the right wax vs. a ski with the wrong fit and wrong wax. Handling pressure/stress, tough conditions, travel, nutrition, hydration.... these all parts of "performance."
It's not about VO2max.
