The 35kg and 69 kg tie in with the EASA "Holiday Charter " figures quoted in the 2009 survey I linked to upthread (I've also C&P'd that link below).
If they are using still the numbers from that matrix then for it's 83kg for a "standard" male...but obviously that is subject to confirmation.
Looking at our local (Southern France, not far from the Med,) general population I can see how the numbers might still be credible for a charter from the airport to say the Balearics ...elsewhere.
