My real osu! rank after not playing for 3 years

I used to be rank 500-600 on osu standard at the end of 2017. Then I stopped playing the game for 3 years. Sure, my rank has decayed to rank 2700-ish right now. But what IS my real rank? Clearly I can't do the scores I used to anymore. So what is my real pp amount?

Let's speedrun getting as much pp as possible on a private server!

FAQ:
What's a private server?
Just a different server from Bancho, which means I start from zero again. Peppy doesn't like private servers though, so I'm not gonna tell you how to get onto one or how to get onto it. I'm not advertising this at all. If you can, you're better off on Bancho. Private servers have security issues and all the banned players play there lol

Is this multi-accounting?
No. Not really.

What skin are you using?
One of the... 200 skins here:    • 100 osu! skins in ONE video!  

What's that pp counter?
It's an overlay for OBS studio. You can get it here: https://github.com/l3lackShark/gosume...
