The Most Important Cue in Disc Golf Throws is Avoiding Jerks. (My Opinion)
In physics, the derivative of position with respect to time is velocity. This really doesn't mean much other than fancy words. The 3rd sequence of derivatives has a very fancy name it is simply called Jerk (rate of change in acceleration). I believe the jerk creates more issues with the disc golf throw than anything else. This will be a long-winded explanation of something very simple and intuitive for many good disc golfers, but also not understood by the average disc golfer.
Jerk - Is the rate of change in acceleration. The best analogy I can think of is picture 2 scenarios of a car pulling another car with a rope
Scenario 1 - Pulling car accelerates rapidly with the rope lose until it loses all the slack and jerks the car forward this is a high rate of jerk chaos ensues.
Scenario 2 - The pulling car accelerates until it feels the rope tighten the car keeps a steady pace that keeps a constant equal pressure (less jerk)
Scenario 2 is what you want the disc golf throw to be, and I believe is the most critical element to timing. Both scenarios have a feel and once you realize how to replicate scenario 2 the game becomes easier. If you think about player like Ken Climo, Barry Schults and even to some degree Paul McBeth, Ricky Wysocki and Simon Lizzote they didn't have 800 videos describing disc golf timing. They had to figure out what felt right and their forms all came out as what we would call good form. This was probably largely based on feeling and mindset.
Scenario 1 causes horrible aim (especially on shorter shots). It also causes early releases. It doesn't just mess up backhands it bad for forehands and horrible for putting, so it effects nearly every aspect of the sport
The best why I can describe the feel you want is you should try to constantly feel the weight of the discs forward inertia never allowing the disc to have slack within the pull. The same way a string or towel will stay in the air as you pull it. If the rate of speed changes to drastically the string will accelerate to fast and create slack as the speed can't be maintained or you slow down the string won't stay up.
Some people say the disc should be heavy while you throw others say it should be lite. The truth is both are correct they are just talking about different forces. The pulling force should feel like it has a constant weight but the force of gravity pulling it towards earth or in other words the feeling of holding the disc up should feel weightless. This is a balance of the forward inertia holding up the disc.
One of the biggest causes of the jerk in my opinion is starting to pull through to early. The disc will have loose rope forward momentum before the brace, but once the plant foot lands the arm speeds up causing a jerk the disc becomes light and then heavy again often causing early releases and robbing linear acceleration. I fixed my early pull by focusing on keeping steady linear acceleration not by focusing on delaying the pull until the plant. Mindset of what I am doing always works better for me versus step by step thinking of how to throw. I can't say step 1 plant step 2 initiate hips step 3 maintain shoulder speed that allows disc into power pocket etc. This is just too much thinking not enough throwing. Basing my timing on feel has eliminated the need for thinking.
The good news is this actually easy to practice. Start off short since it applies to almost all distances Throw standstills a hundred feet or so while strictly focusing on the feel of the discs linear motion keeping a constant rate of acceleration like a car being pulled by a rope. What also helps me when I do this is picking the point I'm trying to maintain the motion through which is usually 11 O'clock. Also, try to accomplish this same feeling during putts, it makes the putt feel 10X better and the feeling is easier to find during putts.
I think of it as the mindset required for proper timing. Some people might see this as common sense and already do this while others also might see this as common sense and think they do this, but they don't. Additionally, if you are not putting yourself in proper position with basic form mechanics the jerk is inevitable.
