The point was why are they so low, which they aren't.
Fair point, what people haven't realised with Surly's Stack and Reach that it does not included the headset*, which add around a centimetre (Chris King headset stack is 33.95mm).
This is where Surly's sizing is consistent funnily enough, the Stack correspondent with the seat tube length (56cm Cross-Check have a Stack of 556.5mm).
Add a headset, the Stack will be over 560mm.
*To be absolutely fair, a lots of manufacturer don't included headset stack either
