“I have never gone to the local shop” would mean I went to the shop with a frequency of zero times whilst “I go to the shop every month” could mean I go to the shop with a frequency of 12 times a year.
This is fine when we consider the shop and I as discreet definitive objects of a stable unchanging state. So it’s useful in a pragmatic everyday life sense.

But what about in a physical, scientific, more accurately objective sense. I am an open system and so is the shop. We both exchange information and material with the external world and interact with the environment so that the shop and I of last month are not the shop and I of the next. We are in a state of flux changing in both material composition, Spatio-temporal location, organisation and structure, regulation and even behaviour and function.

So in essence what “I” visited what “shop” with a frequency of “anything”? - because both parameters have changed. The initial starting point of the frequency is the shop I’m in at the present moment. But once I travel away and return I’m not returning to the original starting point. Can I truly say then that anything has an actual frequency more than zero - a state of pure unrepeatable flux.
