Ok, so for us slower people (the Captain and I are busy setting up between legs, can't spare too much time - at least that's our excuse!) are wondering if slowing from (say) M.76 to M.73 will make any practical difference to perceived ride quality?
The Captain
says he reckons so. I reckon it's more a mental thing (M.76 to .73 is only a couple of knots, ie only a small percentage?)
Settle this for us - and not with 'the Captain is always right!'
