I finished my 4 weeks last week (this post is late, busy 'n all that) and I'm unquestionably more confident than when I started.
My thanks goes out to Mark Ellis and Discraft for publishing such a great lesson on putting.
Also to all my buddies (Team Rio Don Do) who have practiced with me.
I've found my form, I've found and addressed a ton of issues with my technique and now it's just a matter of practice and patience.
The results have been great.
Started about 12 feet or so from the basket on week 1 and honestly, I was dropping putts way too often.
Now from about 20 feet I'm making more putts with better form and waaaaay more confidence then I was making from 12 feet on week one.
It's hard to quantify something without empirical evidence but even without analysis of gathered data, I'm making more putts from further out and it feels great!
