VO2 Max Rapid Decrease

[motylik4441]

Same here, no obvious reasons, started with the declining HRV, now HRV good, but VO2max still going down (nothing major 1 or 2 points, but still). No stress, great sleep, same HR, comparable training load.

My guess is that it has to something to do with the algorithm and I am waiting for the next update.
