And depending on the person it can also change depending on diet and mixing microbiomes. Back when I lived with roommates my frequency changed based on who I lived with to some extent, matching closer to their frequency without changing diet (since I was weight training my diet was controlled and I didn’t eat their food).
Now living permanently with a spouse it has settled on a higher frequency than I remember before moving out on my own. Weird stuff.
That's wild, my frequency has remained pretty consistent through my life, although I did have a couple years where somehow one of the days each week I'd do it would always be Monday, and I never had any explanation for why that was the case.
Not really a constipation but if out of nowhere I notice what I didn't #2 in a while what means I have a quite severe cold incoming - but yet without symptoms.

Social functions, a specific food or beverages (Friday drinking night? Not to the Monday though...) on some days, travel for some.
I don't drink at all, and I honestly don't go out very much ever (including back them, probably very much related to the not drinking thing), so I wasn't consistently having the same thing to eat over the weekend. Interestingly, this did coincide with the period where I was going out to a specific event every Monday night, which is the only reason I remembered; I would be thrilled when it managed to come about during the workday rather than in the evening when I was out.
