Re: Regional Pressures

You are not comparing "like" with "something like" in your original question. To compare a RPS with an aerodrome QFE is quite irrelevant. However, a cross-check with the current aerodrome QNH would be more useful to ascertain that you - or the Met Office - have not made an error. The RPS should always be either the same (possibly) or numerically lower for reasons that have been explained.
PS - why this obsession with QFEs and RPSs?
