Your method consisted of his method with a few other pots, so just saying your method will waste money isn't kind of contradictory. Your method INCLUDES his method, just adds 2 potions to make first. Nope, making every super potion will use a lot more money then making your most efficient potion, selling them, then buying ingredients for extremes. Also skipping out on spec rests and super antifires is wasteful because they are two of the cheapest potions. His method will cost a decent amount more, I cba to do the math but I think it's at least 10-20m more if he plans to go to 99 like that.
