Oh yes! Don't worry about it. You do have fewer cr@p days as the years roll by, but you still have them, at least i do - especially with aeros.
Some days I go up and it sings! The flying is great, the aeros are super, I'm 'in the groove'. Other dyas, it just doesn't come together like that, and even a simple loop is awful. Trying harder makes it worse.
Days like that I land and save the money for a better day.
