I've always been under the impression the more you do something, the less you need to think about it, and the more 'head space' you have for analyzing your predicament.
The first time I polled around a transport category aeroplane, my mind was completely occupied with how to fly it, what to say and when to say it, checklists, SOPS etc. This lasted for at least the first 500 hours (on type). My total time was around the 2000 hours mark at that stage. After that, everything was ingrained, I didn't need to think about what I was doing anymore, and could concentrate on the 'big picture', my decision making, the overall operation, company needs, crew needs etc etc.
At 200 hours I was still learning how to be a Pilot, I certainly was not ready to fly a jet.
