Damn, if you went by that graph, alone, it almost seems like there were growing pains with getting the Demo to work for him(longer chainstays, etc). Of course, there's other factors that we don't know about.
Don't need this graph to know that he had major growing pains with the switch to the demo. He couldn't even decide what size to ride at the beginning of their first season together. Then he said he wasn't training on challenging enough tracks. Now that he's clearly got the demo figured out, I find it surprising that he's willing to switch teams again, and risk another adjustment year.
