i'm pretty sure you would need way more data sets than you think, and thus all the trends you would see would not correspond to reality.
MY TIPS FOR THE SAKE OF YOUR GUYS KNEES!!!!!!!!
I'm noticing alot of p 18s and high din bindings and I know most of you probably weigh between 140 and 175 lbs. I also know several people (I can name names) who have blown their knees when they didn't have to because their bingdings cranked way the fuck up because they were conserned with pre-releases. Here are my tips for you:
1. Your bindings are most effective in the middle 50 percent range of your din setting. Aka if your din is from 8-15 you should be riding them between 10 and 13. If they're at 8, your ski is likely to pre-release like crazy and if they're at 15 they are likely to stay on spesh in a low speed crash.
2. Make sure you have the proper forward pressure on your bindings. You have to continualy adjust this because hard impacts and vibrations will slolwy back off the screws. I do mine every few days to a week of riding. If your forward pressure is adjusted properly you will not have to worry about pre-release and you can ride the din your supposed to.
3. Not about your binding set up, but fucking stretch, that is so important and no one does it.
I'm 200lbs, I currently ride on 181 S4's and 178 S5's both with Rossi axial frees' (din range is 8-15) and my dins are set at 10.5! I don't even think I had one pre-release last season! And I've never had a knee injury from skiing (knock on wood) and I rode in the WSI big air, Triple Challenge and Midwest open and scored pow and park at 13 different places. On top of that all my old Axials 120s are set at a din of 8!
Hopefully this helps
