Lewis has had less time than Jenson to hone his skills at this top level so he's probably going to improve even more than Jenson as the years progress.
I disagree. An illustration of his carreer form so far would look something like:

IE steady decline. No longer can anyone expect Hamilton to settle for consistent podiums, remember his mini-run of 16 points in 5 races in a winning car? Being left behind in Q1 or getting lapped most races was another. Even poor Kovalainen could manage better sometimes. Lewis' became more erratic, and his rain form seems to have disappeared altogether.
Jenson's career has been completely contrasting. A young diamond in the rough turned to all-round driver, with the ability to perform with extreme consistency. His run of 7 races last year were as good as anyone's through F1 history. That's the sort of improvement Jenson has gone through, and we should expect more this year
