Yes, but BA's tables are not really relevant to a RY thread and were only mentioned to emphasise the message that they did not always show the 'truth'. This is clouding my message - "why not try PLOG (or PLOG+300) and see what happens. Let me know if you die".
As a further anecdotal irrelevance, I once flow with a BA skipper who REDUCED PLOG fuel by nominating LPL as a (westerley) MAN div instead of the EMA fuel printed on the PLOG. Sheesh! Oh yes - we didn't die then either.
