I tracked intake, calories burned(from Apple watch with activity tracking turned on for any specific exercise) and weight for 12 weeks as part of 75 hard and found my daily weight decreases were exactly in line with what you'd expect given the estimated deficit 95% of days and 100% at the weekly level.

I don't track consistently anymore only when I'm working towards a goal but when I have more than 2 weeks data these days it seems pretty spot on to the point I can calculate the tracked captors to target to get the desired rate of change in weight pretty consistently.
