Wingspan isn't FM data, it's structural data.
About max speed, for each plane type you can find different sources giving you different numbers, and even different reference altitude for max speed.
... and that's including different real flight test data.

Ahah.... and do you think your link gives the only valuable and universal source??? you must be kidding...
Have you tried, just for ONE type of plane to gather all different performance sources and to compare them... you should try, it will help you to understand the problem...
