What do I need for 6-hit 100TP gain?

[Malacite]

Why the complexity though? It's easy enough to attain 46+ with just the Hachiman gloves.

Unless you don't swap gear in WS.
I use less STP equipment on WS, more concentrated on STR.
No Chiv Chain but gorget
No Hachiman Kote but Pallas/Alky
No Hachiman Sune-ate but Rutter

[W.o.t.W.]

That's because you're not as lazy as a regular human being. Nonetheless, I think you've settled the math; macroing in gear is up to the person playing.
