More depth to cam profiling

actually I would content if instead of having an arbitrary 0-100 system for the cams it was listed in duration. Duration would make sense as when looking for cams that’s the first thing you look to to gauge the aggressiveness. of course there’s a lot more to it, but if I knew that my “65” cams were actually 264 duration and my 100 cams were 320 duration that would make it easier to make a real world connection, especially when you are trying to recreate IRL engines.
