Well, I've been playing for 3 years this christmas and I started out having awful rhythm and about last year it turned to just bad. Recently (within the last 3 days) I've been practicing with a metronome constantly, and just running through my normal doodle and play time. I feel that already after 3 days my rhythm has improved tremendously...could this be possible? Is it all in my mind and I'm still off every 17.4 beats? I'm just really happy with the increase and it's seemed to boost my creativity. So....could the metronome have helped so fast or am I still gradually getting better timing?
