I thought it might be of use to explicate how this game plays out when I do it. This morning, I used 5 discs starting at 7 meters and played five rounds, which took 15 minutes or so. After the first round, I had 1 disc still at 7 and the other 4 at 8 meters. After the second round, I had 3 at 8 meters and 2 at 9 meters. After 5 rounds, I had 2 at 10, 2 at 9 and 1 at 8. I never missed all three putts, but overall I wasn't putting that great during this session.
EDIT: It may be worth noting my practice basket has no outer chains so you have to be pretty much dead center and at the correct speed for it to catch.
The most challenging putt is making the 3rd one after I've made the first two- sometimes I get careless and other times I get worried about missing it. I enjoy that the game has a built-in "high pressure" shot.
I then played three rounds and putted really good overall. I made a high percentage of putts from 10-12 meters and stupidly clanked a couple downhills from 8 meters or closer. I had one crazy tree-to-tree hole that got away from me but other than that I don't think I had any 4s today.
EDIT: I have since remembered I had two other 4s, both 500-600ft technical holes so i don't worry about that too much. (long tees, long pins 10 and 11 peninsula park, iowa city IA)
I think the game is worthwhile to promote because it really has improved my putting overall. For me, just being able to see objective progress over time is useful, as opposed to simply putting for fifteen minutes without any consideration for how many shots you are making or what distances you are making/struggling with.
