This is a very interesting subject.
It got me to thinking about my own experience with recency.
Many years ago I was the training Captain for a waterbomber company and each new season when we flew the first flight with a water landing and pickup I found myself suffering from what could be best described as flare anxiety. Flare anxiety is the only description that I can think of because I had lost the confidence to be comfortable with the low flare necessary for a proper touch down on the water.
However after several approaches and touch downs I was right back to the same level of skill and confidence that I had at the end of the previous season.
So recency is very important for confidence and proficiency.
Now there is one exception, that is sex, the longer I am without it the more confident I am that I can do it, however the lenght of time that I can do it reduces drastically.

The hardest thing about flying is knowing when to say no.
