Don't get all this scores improving questioning. Putts per round may improve but if other aspects of the game are off on any given round then surely scores and handicap won't improve. It's a multi-facet sport and putting is just one part of that surely. I know from my own experiences you can have a 30 putt per round game but if you're struggling off the tee or missing too many greens it isn't really going to help the score excessively
