Sorry for the delay in replying. I would love to share my time line program and see what feedback I get. Some family members have seen and used a couple of my programs, but they don't tell me much so I would love to hear what enthusiasts and experts think (just be gentle with me!!) How can I get the code and data to you?
The program is 40k. With the data for 2 time lines it comes to 284k although some of the data is duplicated for reasons I won't go into here. I am quite happy to share it all with just a credit for the work.
