Thank you for spelling out the reasoning rather than just the conclusion. Adding it to my notes with a link back to this thread.
Clinical perspective, offered as context rather than as advice. Order of operations matters more than any single choice here: establish a baseline, change one thing, wait long enough for it to express itself, then measure again under the same conditions.
If somebody has the primary source to hand I would rather cite it than paraphrase it.

Can confirm. Same sequence, different timescale. Nothing to add that would improve it.
Certified reference materials, analytical reagents, and research-grade standards for peptide verification. Trusted by laboratories worldwide.

Adding the part of the answer the thread has not reached. The distinction that resolves most of these threads is between what is true on average and what is true for one person. Both are real; they answer different questions and get quoted as if they were the same one.
Closing the loop on my own question.
Reporting back with a partial result, because a partial result is still better than silence. Two of the three things suggested helped; I cannot separate them and I am not going to pretend otherwise.
