I was looking on runetrack and saw people getting like 3-5m farm xp a day!! How do they do this??

Those 3-5m experience days in farming are all-time records. Something people plan out well ahead and nothing that can be done regularly.

 

For atleast some of them I know are effigies opening, I think atleast a few people spent 300 or more effigies on farming to be on the record board back when you could stock them.

 

The larger records though come from Vinesweeper if I recall right, I don't recall any point limit (or if there is one its quite high) so if you enjoy the game and want the record then save up a few months of Vinesweeper.

Ahh ok
