If you want to go for the body recomp method, which means slowly trading out fat loss with LBM and hopefully muscle gains (slow meaning less than 1 lb a month if at maintenance, longer if at deficit), then you'd want the 24 hrs post workout to be higher.

You can accomplish that by using the MFP method first, still with reasonable deficit though, to at least eat more on days you exercise, calling a day 24 hrs post workout.

That may require just shoving more of the days calories in to that range of time, unless you lift in the morning.

But ever better, is slide 250 calories 24 hrs prior to lifting time, and in to time 24 hrs after the workout, so even more during repair.

That's about as good as you'll get without bulking by eating above TDEE.

As to when your body is too stressed to do that with low fat, never seen any studies point out when it happens exactly, you just kind get what you'll get, since everyone is different.

Along with measurements take pictures. Pick an outfit and use same outfit, angles, poses, and distance from the mirror. During recomp you can measure and not change in spots you consistently measure, but have fat loss above or below measure point. So pictures are crucial during process.
