This is going to be my fifth season skiing, and I'm still around the intermediate level, mostly doing blues and a few mid-atlantic blacks when things are not too icy. I tend to be relatively cautious and slow, unless I'm somewhere with great cruisers and conditions (like Stowe).
When I had my bindings set on my previous pair and on the current, I kept listing myself as "beginner" and I've never had an unexpected bindings release. They only released in situations where I'm very glad that they did. Since many people set them higher to avoid unexpected releases, I'm starting to wonder if something is wrong with my skiing

Am I doing the right thing by keeping the bindings set for beginner for now?
Also, is there a way to force the bindings to release as a way to test them? They've been tested in the shop, but I'd like to try in less problematic conditions before I actually need them to release.
