Recovery ride everyday?

I have started to get a little bit hooked on an easy recovery spin on the trainer while watching TV with the wife at nite.  Nothing serous, just 15-20 minutes on a very easy gear and 80-90 cadence.  Not enough to work up a sweat, but enough to get the legs feeling nice and loose before going to bed.  I focus on smooth circles and occasionally throw in a little bit of 1 pedal practice.  I am starting to do this almost every night of the week as it does not cut into my training time or family time.  My logic is that it:

1)  Helps to promote recovery by getting circulation up to flush out the junk and move in fresh blood.  The way my legs feel afterwards is proof positive.

2)  Has a very mild training effect in that I am repeating a muscular movement that is incredibly sport specific, improving muscle memory, while not increasing actual training load.  Better muscle memory=less effort to perform a motion as it becomes more natural.

I can't imagine there is any downside here, but would appreciate some input from those more experienced.  Even at an easy pace am I still introducing stress that may lead up to over-training symptoms?  Or is this workout too easy for a fit and "trained" person?

Thanks in advance.
