Yeah I just meant without logging out. It can be done with construction using proteans and prayer with frost dragon bones afaik. I can't think of any others.
Demonic thrones - 17m/h
Summoning - Talon beasts, un-noting at Taverley - 12m/h
Herblore - Overloads - 1.4m/h (900k/h from scratch)

Some of these, mainly higher xp rate ones, are basically just trivia, and are horribly impractical. Demonic thrones, for example, cost 12b/h.
Just a list I found online, pretty sure its rather accurate, obvs the Dg is highly variable. Unsure about smithing, dragonfire shields used to be decent efficiency. Cutting dragonstones is a bit slower then onyx but you can buy those more easy on the forums.
Most I botted in a week was 4 99's from low 80s or so; craft, smith, constr and cooking. Around 3 years ago though.
