My normal routine is this, and it has helped quite a bit. It gives me something to strive for and keeps me in range to sink putts consistently. I have just over 30' to work with in my basement (still waiting for spring) with every 5' marked from 10-30:
- Put 15 minutes on the clock. Enough time to make it worth while - but not so much that I lose focus.
- I use 3 discs
- Start at 10'
- If I hit all 3 - I move back a line. Hit 2/3, I stay there. Hit 1/3 - Move up a line. Hit 0/3 - restart back to 10'.
- If I hit all 3 at 30' I "win" and call it for the session. Nothing like that for a confidence builder.
- Goal is to 'win', but if not, to end on the furthest line I can.
So far I've only won 1x, but that was a great feeling. Usually I end up on 20 or 25 when time is up. 10' are gimmes. 15' I usually don't miss. 20' starts to push it - I'm currently about 40% hitting all three - 50% hitting 2/3 - 10% hitting 1/3. At 25-30 it really depends on the day but accuracy goes down quite a bit. The 2 things I like about this setup are:
1 - It builds pressure (otherwise hard to simulate in practice) as there is nothing like having hit 2/2 and knowing that last one from 30 will "win" the game.
2 - It keeps me in ranges that allow me to be successful but are not all gimme's. And once you do have a bad 'round' you move in 5 feet and almost always go 3/3 which is great for confidence.
