I guess when you think about it too, all this stuff is going on in places where people don't actually skate, eg the manufacturing end is just what they get told to do, so who knows if anyone is actually measuring those boards, or they just get the deck lot number that has been matched up with the sticker lot number of XXX number of units each.
When I was in the warehouse of a massive retail production, the number of times I noticed the barcode stickers we were allocated to put on the stock were incorrect to the product, then was told to use them anyway as that is what we were given to put on and not ask questions that would slow down or halt production, I felt like quality control was almost out the window.
Sure it was still the right brand and price, but things like specific colours or other info were wrong, but that appeared to be my issue, not theirs and we just had to get them on and out as soon as we could.
As was said, if someone changed the request for different length, wheelbase or whatever, they would still have those stickers to put on the boards regardless, which could mean the dimensions were incorrect, which would bug me to no end, but maybe the general public would not have a clue and just buy the board for the graphic, for the pro dude or whatever.
Either way, it is interesting that there are repeated differences in measurements on a number of threads about boards more recently.
