You know what, I've been going by my "active time" counter, that's what has me at a bit over 25 hours (and like 11,000 calories). Next time I have my Switch handy I can check the overall play time.
I just fired up RFA (wish I didn't have to strap up the left joycon on my leg to do so) and had completely forgotten that the game gives me those stats when I select myself as the user. It tells me:
19:10:35 time
6629.25 kcal
40.90 miles
Quite a difference! You are probably around 80 hours of game time overall then!
