Now what we've suspected all along is official: Boeing admits the methodology they use is wrong. When you have 4 pilots in the cockpit with combined experience of 50 000 flight hours, wide body, the works, and all of them perceived a landing as merely "firm", but the sink rate report claims it was "hard", there must be something wrong.
So, chill out, boys end girls, nobody should doubt your professional abilities!
Cheers!
