A couple of years ago, I saw some people run 100 Gold Skulltulas. I wondered if people were also doing 20 Hearts, but I found no videos or routes whatsoever.
So I decided to make a route myself. I might have overlooked some things and it's definitely not optimal, but it's a good starting point.
The route, along with the rules and timing method, are in this pastebin:
