Yes sure - but they don't see it that way. I'm always up to learn something new, but I need time to digest it and decide whether to incorporate it. I feel checker outers (to coin a word) should try to add to and build on your existing skills rather than trying to replace them.
When you're on your own at a new airfield you have to figure out everything for yourself (with the help of your Pooleys guide). You don't usually get it that much wrong and that should be the starting point.
