I know you mentioned you don't like using your smartphone but that's how I do it. I keep my hcp and statistics with the oobgolf.com android app. It's very user friendly, quick and easy. You can choose which stats you'd like to track and I chose sand shots, penalty strokes and putts. GIR is calculated automatically if you track putts. When you go to the website to view your round afterwards you get more detail which I love. Congrats on getting to a 31 in just a couple months, that's where I am and it's taken me a year.
