Hey Sunkight, I’ve been working on a quick model to predict the best spike angle based on wind speed and ball velocity—just a little data crunch. Got any stats or video footage from your training that I could feed into it?
Sunkight
Sounds sick! I’ve got a bunch of replay clips from my last sets and some raw numbers on spike speed, jump height, and wind. Just shoot me a DM or drop the files here and I’ll hook you up. Let’s get that model on fire!
Meiko
Great, just drop the clips and the raw data here when you’re ready. I’ll run it through the model and see if we can shave a few centimeters off your launch angle. Looking forward to the numbers.
Sunkight
Sure thing! I’ll drop everything in the chat folder.
**Video clips**
- “Spike_Set1_2025-08-12.mp4” (short 3‑min montage)
- “Wind_Test_2025-08-13.mp4” (4‑min clip of me spiking in 10‑mph wind)
**Raw data (CSV)**

Drop these into a folder and let me know if anything looks off. Can’t wait to see what you pull out!
Meiko
Sounds solid—I'll load the CSV, pull the spike angles, and start fitting the wind correction factor. Let me know if the footage is encoded properly; any playback issues might skew the angle extraction. We'll tweak the model until the predicted launch matches the real spike. Ready when you are.
Sunkight
Absolutely, hit me up with the results—let’s see if we can shave those centimeters off the launch! If anything feels fuzzy, just shout. I’m all in for the next win.
Meiko
Got the numbers: the regression comes out to about 1.6° per m/s of wind, or roughly 0.7° per mph. In other words, every mile‑a‑hour of wind pushes your spike angle up by about three‑quarters of a degree. The intercept is around 31.9°, so at zero wind you’d be spiking at just under 32°. We can use that to back‑calculate what launch angle would be with a clean wind, and tweak your approach by that difference—maybe a half‑degree lower for a stronger gust, or even a full degree if you’re running into a 10‑mph breeze. Let me know what you think and we can adjust the playbook.
Sunkight
Nice work—wow, 1.6° per m/s is a solid find! That means I’ll just angle up a bit when the wind’s blowing. For a 10‑mph gust, a full degree shift is doable, so I’ll swing my jump a smidge higher. I’ll run some mock sets with the new angles and see how it feels on the sand. Thanks for crunching those numbers, we’ll tweak the playbook and get a few more points in our favor!
Meiko
Glad the math works. Just remember, a half‑degree tweak can feel like a whole different swing, so keep an eye on timing. Hit the sand, collect the data, and we’ll re‑fine tune if needed. Good luck!
