Any timing experts out there that can explain some some timing paremeters

[conoco]

I was hoping someone on the forum could help explain the different timing parameters and maybe some base numbers I can start with on my new distributor.
I just installed the Progression Distributor and I can now control timing on the fly or make different timing tables for different driving. I know just your standard intial timing and all in, just the basics but could use some help explaining the different values with this new distributor so I am able to get the most out of it. Here is the different tables I need to populated. I would like to have a table for cruising around town and being able to get into the throttle a little bit and also for highway driving. Any help with explaining the different numbers would be awesome. I am trying to research as much as I can but can not get explanations for some of the values and I am kinda lost

So far with just the auto set up my truck is running way smoother, I have not driven it yet, waiting until I get the gear vendors unit installed. Thanks everyone.
