Precursor Forging Tool

I am not sure of these numbers. I am 100% sure the listed ingredients are the cheapest to make the desired precursor, but I am not 100% on the average number of tries to get the precursor (the current estimate is from other people publishing their results - mostly from reddit's Nugkill).

Help and Info:
 ● Gives a list of all precursors for you to select, then tells you the cheapest ways to make the precursor you selected by throwing them into the Mystic Forge.
 ● The top combination will have all purchased ingredients. The second combination will have 1 crafted and 3 purchased ingredients. The third combination will have 2 crafted and 2 purchased ingredients. The fourth combination will have 3 crafted and 1 purchased ingredients. The last combination will have all crafted ingredients. You can pick which you want to use.
 ● 'Precursor' is which precursor is being made, and the buy order and sell listing prices for that precursor.
 ● 'Price to MF' is how much it costs to buy all the ingredients that will give you 1 precursor (on average). % profit is if you're selling it. The price and number of items assumes you re-MF any products of failed attempts.
 ● 'Ingredient 1,2,3,4' is which are the cheapest ingredients to throw into the forge and how much to buy or craft them.
 ● These are all averages. That means there will be times when no precursor comes out for 1000 attempts, and times when you get 2 in a row, for example. The strategy is that with a statistically significant amount of tries, you will observe the average return.

Precursor Drop Rates:
 Drop rates is from research posted on reddit from the production of 289 precursors.
 1 in 5 promotes rare to exotic, but appears to have less chance of getting a precursor
 Average level of ingredients needs to be at least 75 to guarantee a level 80 (and thus, a precursor)
 1 in 139 attempts produces a precursor from exotic (start with 416 exotics, including throwing failures back in)
 1 in 781 attempts produces a precursor from rares (start with 2,342 rares, including throwing failures back in)
