Undergrad How the standard spacetime model relates to reality

[Nugatory]

Are you suggesting that in the block universe interpretation of the mathematics, that there is a distinction between what I was experiencing while you were experiencing what you were experiencing and simultaneity? Such that event A being simultaneous to event B does not imply that a witness of event A, located at the location of event A, would have of experienced event A while a witness of event B, located at the location of event B would have of experienced event B.

I don't know any way of answering that question until you can provide a definition of that word "while" that I've bolded above.

If you are asking for a definition of how you could tell experimentally what I was experiencing while you are experiencing then the answer is I'm not sure that one exists. But in both cases I used it, I was assuming that the experience of each person was changing, and was considering what the one person's experience was as the other was at a certain point of their changing experience, or during a certain period of their changing experience. They don't have to be experiencing clocks or if they were what they experienced the clocks doing doesn't come into it. It is related to the idea that other people are experiencing change in parallel to your experiencing change, that corresponding to your experience of change, other people are experiencing change and so on. I presume these aren't exactly alien concepts to you, so if you aren't able to understand, perhaps you could highlight what is causing you confusion? If you think you can understand, then you should be ok to answer.

Such a definition does not exist; there is no such experimental method because, as I said, "simultaneity" is not a physical thing; it's a convention.

The discussion is about the interpretation, not the maths.

Then it's off topic here. We discuss physics here, not "interpretations" that make no difference to experimental predictions.

I don't see how having different "static perceptions" at different points along your worldline is having a changing experience

It is because the model says it is; that is how "changing experience" is modeled in SR.
