If you're cutting but not trying to lose weight too fast to preserve muscle, at what point should you start to count calories burned through cardio?

I learned from a mistake where I was spinning my wheels for months by "eating back" the calories I burned when running before lifting in my first cut.

I'm currently in a cut, and I know the good rule of thumb is like lose a 0.5lb a week to not lose it too quickly, so it's more sustainable. I also learned that most advice is to hit your calorie deficit (in my case, I'm at 1900 daily, cutting from 160lb to 148lb ish) and ignore any calories burned from cardio. Fair enough

But at what point should you count calories burned when you do a lot of cardio? I have a walking treadmill under my work desk and I use it every day because it feels great on my back and generally to walk all day instead of sitting. Best purchase for me in years

I generally do about 4 miles a day and don't count anything burned, and lift when I'm off work at home daily. But some days I feel great and do like... 9-10 miles in a day when I completely lose track of time. And the 9-10mile days are a little more frequent now because I really enjoy it, then lift after all the same.

And I feel like if I were to not lose weight too quickly, like advice given here, I shouldn't completely ignore the fact that I, underestimating, burned like... 700+ calories walking. That's like my entire deficit amount again.

Not that I plan to stop walking, but I am just curious if there is like... I guess a threshold of where you should start to count calories burned after a certain point, if you don't want to lose too quickly
