For those interested a reply from Never Summer Product Development which I was authorized to post here:
You measured the board from the tip to insert and tail to insert and it is 1cm off ( which means it is around 5mm offset). All of the cores are sanded with an AEM programmable CNC wide belt sander which is calibrated by a computer so the core will be perfectly twin in flex. Inserts however are drilled manually and so small variances may occur. We measured twin boards from other manufactures the other day and there are often variances on any board that is hand made. The variances can be compensated by adjusting your stance with the bindings. Our acceptable variance is within 3-4 mm(this would measure between 6-8mm difference in tip to tail). If you feel that your 5mm offset is adversaly affecting your ride please let me know and I'll create a Return Authorization number for you to send the board back and we'll exchange it out, no problem.
