my 2 cents....
....for what they are worth is that, as stated above, Cal is still struggling to find a setup that gives him the feedback he needs to push on to his limits and the bikes limits. With the current setup he's hit a false-ceiling as it were, where he's unable to extract the most from himself or the bike. We know the M1 can do more and his shouldn't be that far off factory spec.
I also think Silverstone, or the upgrades to his M1, came along at the wrong time for Cal. The pressure he put himself under to get a result at Silverstone meant from FP1 he was pushing as hard as possible, and without having his setup nailed he was lacking feel and started crashing.
I agree Benny/Rob/whoever, the only way Cal will be able to find the right setup for his M1 is if he stays on the thing, and it would be easy for him to wobble around in 8th place and not risk a crash but we know he isn't that kind of a rider, but unless he pushes to the limit he won't find out how the bike feels at the limit, or where that limit is, and sometimes that means you have to crash to find the limit, then only push as far as that limit.
Rossi is still trying to find that magical setup by all accounts, but he seems unable or unwilling to push early in the race until the setup comes back to him, which is good as he doesn't seems to be risking a crash like Cal does.
Is that where Cal is going wrong? trying to push for a podium when his setup come raceday just doesn't justify one? Or is he just riding beyond his limits? I think it's the former, we know the man has talent, and I think once he has his setup sorted he'll be back up at the sharp end again where most of us want him to be.
