Actually they did quote 6 weeks ... end of May delivery (looks to be week 22 in my calendar ... but as it is Microsoft Outlook, it could mean anything).
But, when they broke it down, in best case it worked out more like 4.5 - 5.
So yes, the did under promise ... but then they also set parameters for over delivery too
So here is hoping for being pulled from a week 16 to 14 build and then 4.5 week delivery ... and for my next trick a flying pig!
