What is the most efficient way of using Golden Gauntlet? (Alchemy Tome)

Before I start, I know what most of you people are thinking, I just use it for daily quest and thats about it. I also used to think like this but with red patch Gold has become very important and you can not fulfill everything with it which includes leveling skills, enchants, forge, buying bronze chest, trade post, etc.

So what is the solution? The new Alchemy tome is the solution, it raises the crit chance and gold income from Golden Gauntlet and Gold mines. I have already 3* most of the tome skills but I wanted to know if I use should use single or multi option under Gauntlet.
