degeneration

Pat007 - worst case, you cut away not realising how your lines are tangled around you, you fall down, but one of those lines ends up around your neck, and that's now taking your full weight. You've just hung yourself. Maybe an extreme case, but if you are unsure, is it worth this risk?

Very nice and detailed comparison! My take from your review is that if you are not bothered about the ultra slo-mo of 120/240 fps or need wifi, then the Replay Mini seems the camera to get. Exclude the scores in those categories for the AS100, the AS100 would only beat the Replay by 1 point, but at twice the price. The Replay scored in two less categories than the Hero 3+, but only scored an overall 2 points less, again at half the price. It seems like an outstanding budget camera - if you are happy to sacrifice ultra slo-mo and wifi.
Any chance of adding an "Average score" column just for the categories they actually scored in?

Debatable! My site - http://jumpticketprices.com/tunnels.asp (which is in a sticky in the wind tunnels section) has got 50 tunnels spanning 22 countires on it just now. Whether they are all active and the completely indoor type, I've no idea.
Feel free to take whatever info is on my site and include it on yours - I'm happy to share!!
