PSMF Calculator and how often to recalculate macros?

Do you all re do your psmf calculator as you are losing weight? I’ve been PSMF for 19 days and am down 9lbs. I’m loosing about half a pound a day which is ok (I’d love to lose more- not sure how you 47lbs in a month people do it ) but I’m not sure if I should be re calculating my macros or not. I’m a cat 3. Currently 172.8lbs, 5’0 ft tall. I walk on the treadmill 30 min a day (usually burn 200 cal) and do weight lifting (kettle bell exercises twice a week) my waist is 42inches (I measured around my belly button) Maybe I am doing something wrong with my calculations? Should I not be walking on the treadmill every day? Is weight tearing twice a week slowing down my progress? Mymacros are :pictured below but I just re did my macros at my current weight and it dropped me to 602 cal, 80 G protein and 20/20 carb and fat.
I am religious about my macros and track everything in myfitnesspal, so I’m confident I am not going way over on anything.

The more you have to lose the faster you will drop the weight as you get to a lower weight it will slow down. Half a pound a day is still 3.5 a week so right in line with the 2-4 pounds a week.

FWIW, those "47lbs in a month" people are generally the ones with the most to lose. Medium-sized people (and you are definitely medium sized) lose slower, and the smaller you get the slower it goes. When you hit normal weight, it really drags - it justtook me 6 weeks to lose 9 pounds! You're doing extremely well, please don't be disappointed in your progress.

I redid my macros after I finished my first cycle (10 weeks), and then 7 weeks into my second cycle I had a major body shape change almost overnight (it was the weirdest thing I have ever experienced) so I re-measured and ran the Navy calculator to check my body fat percentage and lo and behold it had dropped to where I was category 2 instead of 3 so I redid my macros again. I'm a couple of days into another diet break after a 6 week cycle but I'm not bothering to redo my macros because I'm still in the same category so protein won't change and that's the only macro that matters.
