Bear in mind these measurements were done by hand, and not the result of plugging in manufacturer's dimensions, so the measurements themselves may be _slightly_ inaccurate.
In my experience, it's always better to round down if need be because new spokes do "stretch" slightly and you may need the extra mm or so when you retension your wheels after riding them for a bit. If you want me to check your components and get the right spoke length, shoot me a PM.
