Hi all,

  
I was trying to work out whether it's worthwhile boosting from 89 to 90 Runecrafting with Metztonalli white whilst running ZMI. I couldn't find the calculations on what runes would be crafted per inventory in each level bracket, so decided to put this together myself and thought it might be useful for others too.

  
Based off the gp value of runes (2nd column) and having the medium Ardy achievement diary completed and the Metztonalli white taking up an extra inventory slot each run, the 'profit' from boosting each lap is 1,191gp. This is based on the average level 90 loop generating 12,511 worth of runes, a level 89 loop generating 10,820 worth of runes, and the Metztonalli white costing 500gp.

  
There are of course others factors to consider, such as whether you think it's worth the additional effort and whether you value the runes produced during ZMI more or less than their standard gp values.

  
Lastly, I'm assuming 66 essence are used per loop at 89 (40 in the colossal pouch, plus 26 in the inventory - 28 less the colossal pouch and rune pouch) and 65 are used per loop boosted to 90, following the same logic with the addition of the Metztonalli white.

  
I hope this is of use to someone!
