THe thing about jump putt to step up putting is, in a jump put you can replicate a shorter putt's disc travel and landing either in the basket or close. with a walk up unless it goes in or if it hits off the top you can have quite a bit of work yet to do on said hole. Raise your hand if you have ever turned a duece putt into a bogey god knows I sure have! If by throwing accurately from 100' you can lay it up then it is not a putt; if you can put it in even 3/10 your a god. Jump putts for me are bout 50-70' otherwise i'm laying up,if you zing it from that far out and miss see above.
Calling it a jump putt leads to confusion because of a basketball term most people know.
In basketball a jump shot is just as it is named, you jump, then you shoot while you are off the ground.
In disc golf it is called a jump putt, but you are not allowed to jump, then putt...you actually have to putt before you jump, you are not allowed to be off the ground with the disc still in hand.
So a better name for it would be a putt jump, to avoid the confusion.
When you come up off the ground and the disc is still in your hand, do not be surprised if you hear a call...
Just trying to help those people who want to work on proper form and avoid rules issues during tournaments.
I felt it was necessary to elaborate because of what I see on the disc golf course...Jordan putting has become acceptable during casual rounds and becomes an issue during a tournament.
To answer your question for the discussion, No jump putt is necessary. Long putts can be made with proper form and no lunge is needed.
I recommend it. The reason is simple. When you're putting, everything moves in a line. It's tough to get off line with that. When you're 100 ft out and you have an angled landing zone, it's critical to get the right disc angle and landing spot. If you throw at it you have a chance at an early release or late release. Jump putting virtually eliminates this issue. So having a jump putt won't just allow you to make more 40-70 footers, it's a great 'lay-up'/approach tool as well. That said, you can't get sloppy (ie not practicing) with your true approach throws, but if I have a choice, I'll jump it rather than throw it.
