Hi DutchRoll
My question was comparing DP with OEI DP (ie both at same altitude) so wind is irrelevant other than making the diversion quicker/longer. My rough calcs put the difference at about 800kg/hr for B777.
My point is that a lot of pilots say the chances of getting engine problem and depressurisation at the CP is minuscule, but that's not quite the case.
