@capdb you should look into it. It can be really confusing at first, but then it opens up. You said you wanted to understand yourself a little better, maybe this lens will be helpful to you. I don’t want to dump all kinds of info, but if you want to run your chart, I’d use the Jovian archive site first, as some others can be inaccurate. Also, it seems like a lot of the info is behind a bunch of paywalls (which is true), but there is sooooo much free stuff out there, you really don’t need to buy anything.
