Taken in the context of the discussion, there is no "bullshit" in this statement.

In discussions of shotshells when pressure values are noted, they invariably relate to PEAK pressure. Whereas the literature is awash in xxxx psi, lup and cup numbers, only in rare cases does one ever see a pressure trace revealing the total pressure (vs time) under the curve.

Therefore, in the jargon, shotshell pressure unless otherwise specified will always be taken to mean "peak pressure." The more astute readers in this forum would not be confused by, nor take issue with, the quote.
