Just how to exercise for greater up and downs?
 

I've been monitoring when I'm within 50yrds of the pit just how many shots I am taken by it. I only add someone to the amount of putts for that pit, if I access it the green from further than 50yds. Real up&downs have now been unusual, and my average is clearly nearer to 3.5, which demonstrably is extremely poor. How will you exercise for more/better up&downs? Would you discover what your weakness is, split it down to pictches/chips/putts and focus on that, or can there be a approach to take? Thanks.
