I don't do spirals
Yup. Just need to expand on it. I know you have FAQs on the altimeters, but I don't know about the chute release.
I regularly hear how people do a test - and then forget to turn the Chute Release back on. I don't think you point that out in the manual. It's just these little things that lead to a recovery failure.
I think it would be impossible to warn against every possible human error in a user guide. Humorous maybe, but not possible. (Do not eat this product, etc)
