Fitness chart is useless

The fitness chart and relative effort doesn’t take training volume into consideration at all. I’m more fit than I’ve been in years and doing more volume than I have in years and my fitness score is flat because I’ve been in a base phase. In TrainingPeaks my fitness is steadily growing but in Strava my fitness score is flat. Also, when calculating my total volume stop using “moving time.” The moving time calculation is wildly inaccurate. I did a 4.5 hr nonstop workout in the mountains the other day and I only got credit for 3 hrs. Please fix your fitness algorithm. Please stop using “moving time” for anything. I’ll pause my watch if I want to stop moving and not have the time count.
