We all can fluctuate daily. I weight myself every morning, put the weight on my calendar, and go off he averages per week. I will even note if I under or over ate that day.
I know, I've just been a little looser now that I"m not cutting anymore, and yet I'm still not getting fatter.
My training is on point, that is no question. Eyeballing may be lazy, especially during a cut, but if counting macros daily and always weighing shit is not sustainable for a person, they will veer off course. But now that I'm not cutting, I don't feel the need to be super precise, and if I overeat more, it cannot harm me that much, so long as I'm not eating 1000 calories more, which I'm not.
Moreover, What I've done is created meals that I know the calorie content of. But yes, I've been slacking no question about it, yet still not getting bloated or whatever else. My strength is also going up. Deca is peaking now I believe at this week.
I went to Costco and got some steaks and other things, and I will be "cleaning" up my diet more, weighing and all as well... I just took a break for the last few weeks. And being on t3, also made me lazy since it was burning things off, but no longer on it.
