I've been playing a lot more disc golf lately, gradually increasing to what is now averaging close to a round every 10 days or so. OK, not the 20 rounds every 10 days I likely averaged 10+ years ago, but I'm out there when I can, enjoying it.
One of the technique explosions in the sport during my distancing from the sport for a while (raising 5 kids, who has time?) is that of "jump putts". They've existed, in reality, about as long as the sport itself, but it is now a very trendy technique. Essentially, when someone is more than 30 feet out, making it not officially a "putt" (where you are required to stay behind your lie until the disc comes to rest following your throw), a person can jump forward during their throw, giving additional momentum to propel your disc towards the basket.
Here's my rub, though: In the last 12 months, watching some 100+ jump putts, I have seen ZERO go in. NONE. In the same time, I have seen quite a few conventional-stance throws hit the mark. I've even brought this up with believers of the technique, and while they defend the move, they have yet to prove success of ONE effort, much less that this technique has an advantage over a stable-stanced throw.
There are a couple of premises at work here. First, the idea is that less onus is placed on the arm and the wrist, allowing your legs to assist in the energy behind the throw. Second, a jump putt allows one to reduce the distance to the basket for the actual throw. Third, the jump can alter the angle of approach to the basket: an uphill putt will not be quite so uphill, and a throw at a downhill slope can have more drop to it, and thereby not "blow by" on misses. Finally, especially on uphill shots, the jump can help negate a problematic stance, where the slope negatively impacts posture, balance, and leverage.
In my opinion, only the last of these reasons typically can justify a jump putt. Leverage and balance are key to a good standing throw, and if you have little of both, you do not have stability. The problem with jump putts is that while they remove negative stability, they also remove positive stability. When you jump at a target, your advantage of "umph" is counteracted by additional variables: additional glide, more muscles to precisely control, and a large variation on release points. Bottom line: more can go wrong.
Now, I'm sure that many people have used this technique successfully, and I am not saying that the technique is not without some merit; however, if your first question on every short approach is "am I outside thirty feet?" because you are in love with the jump putt, I would say you have the wrong strategy. Low ceilings, slippery conditions, wind factors, and pin placements can all make this decision either foolish or worthless.
My advice? Make your first two questions "What is the best disc to use in this situation?" and "What type of throw will give me the best chance of safely targeting the basket?" If you have an 80-footer, and you aren't comfortable with your putter's accuracy from that distance, then consider a disc with a longer flight first. A longer flight does not always mean longer glide. Some discs can have a good degree of "drop" with not too much fade, resulting in a nice, stable, and safe run at a hole. In my opinion, though, it is very rare to have a jump putt be the best option.
