Annual deck refresh?

Hi!  Last year I labored over stripping off terrible Behr "semi transparent" stain that failed after one year.  After stripping, sanding, brightening I applied TWP 100.  I love the look.  The boards are a bit worn after last year's stripping (I originally applied a different solid stain, it failed, I stripped/sanded and applied Behr semi trans, and now TWP, so needless to say the 11 year old pressure treated boards are getting rough).  Anyway, after one winter the boards still look good, but there are a few spots where the stain didn't take as well as others or it wore off.  Is there a suggested maintenance coat with minimal prep to keep looking good, or only full strip and refinish?  I want to use the same TWP100.  If there is a maintenance step, what prep is needed?

Thank you!
