The strength, toughness and speed bonuses are all relative, so you can get pretty silly values on the right chassis. If you're playing a giant nation, your initial scout can sometimes get hilariously high strength.
With the absolute numbers, I've sometimes dragged out an SP game long enough to get in the ballpark of ~+10 precision or mr, but getting higher is pretty slow, I think, and Awe / Heroic Agility are slower to grow.
Don't know of any way to measure Legendary Cruelty, other than by statistical means.
