I can be at the same pace physically but day after day the times and pace can be wildly different. I can be doing a running workout for 90min and it will say I'm averaging 10min per mile but I only have completed a little over 7 miles according to my fitbit. It seems like my app on my phone is the most inconsistent, I can be sprinting during a workout and the average on my app will be going up and up instead of going down. I've tried deleting the app and then restoring it on my phone and that worked a few times but now it's just so up and down. I can be running at the same pace and one day it will say I'm averaging 9min per mile and the next it will say 16min per mile. It seems to work better when I'm just out on a walk, my times and mileage are really consistent but running on this elliptical machine, it's all over the friggin map
