Can you please explain how you calculate delegation and price?

Unfortunately, I only recently bought 6000 points because I didn't know about this change. Otherwise I wouldn't have done it and I won't do it again, because the points are now worth a fraction. Or I have a thought and math error.

I hope the old function will remain on the website for a few more days and that the votes will still be cast so that I can still use the points I bought somehow.
