Cpp: Yeah! If you or anyone else have a better understanding of what I'm sort of glossing over as "speed points" I would love to add that in. Right now it feels so incredibly idiosyncratic and I like to think it's related to something else I'm just not thinking about.
Flying springs are something I know nothing about, aside from what you wrote on your site some years back. There was another topic semi-recently which had some other behavior which also caused springs to start flying, possibly horizontal springs, but I can't find it at the moment. But I would be happy to port your old article over to JCSref if you'd like. For that matter, we don't have a word to say about waterwalking...
