Experienced kerbals piloting their ships & keeping them steady.

[Tuareg]

The experience level of the Kerbal would have some relation to how accurate a task is executed. Your maneuver requires, say 120 dV. A highly experienced pilot will get within 1 m/s. A moderate experienced pilot maybe somehwere inside a 5 m/s range, and so on. This would obviously be a sliding range based on the experience percentage (but not necessarily a linear relation). In similar fashion it would relate to how accurate the navball is kept on point.

i would like much more if the more experienced kerbals would be able to do more complex things. like less experienced pilot can just go straight with engines on unfocused, a more experienced can do correctional burns the even more experienced ones can dock and the super ones can even land. i would hate if they would do random things for me and miss the duna because it went 5 degrees out... same with rover driving. teach the kerbal how to do it and then let it to do on its own...
