Thank you for the responses.

If I move Lloyd Honeyghan up from welter to fight a middleweight, will the game automatically decrease his HP from 8 to 6?
And if Honeyghan then moved up to Supermiddle, would his HP drop to 5?
Does the game make the same adjustments to all fighters when they move up in weight or are some less affected by it than others? (For example, fighters with overall ratings of 10+ are less affected by upward weight movements than fighters with ratings of 9 or less.)
Are the specifics written anywhere for how ratings are affected in the various career stages? Or for moving up in weight?
(I love this game!)
