I was always interested in zig zag analysis and was about to write a generic zigzag analyzing tool anyways (a zig zag which computes the best fitting zig zag for a period and projects it on the next session). Is there someone coding this stuff for you? By skimming your start post you have a lot of ideas which are actually kind of simple to implement but since there are so many ideas it will take a few hours to get done with it. If you are in need of someone please send me a message next monday evening than I have time to look into it.
