Not even in yet, but I have talked with a couple aviators about this. There is a diminishing return curve, people with significant experience tend to do well initially and then fall off due to unlearning bad habits. People with moderate experience do better, radio comms are tough for newer pilots with no experience. But as the speed of the aircraft increases (down the pipeline) those moderately experienced students will have a harder time. One guy described it like that.
"Don't describe the ocean if you have never seen it." But I have heard this so many times when talking to pilots looking back on their time in Primary.
Hope that isn't too confusing...
