The more HP you have, the higher your RC. It actually doesn't require much HP for you to have a whole lot of RC, so it's pretty difficult to reach that point unless you're endlessly performing actions on the network with about 50 HP.
HP doesn't really exist, it's vested shares of the network you're holding and delegating. So RC is based from that share in the network.
Ah ok! I didn't know. I think I have a fair bit of vested shares so I've never experienced it.
My aim is to get others to that point
