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).

1 Mystic Forge Stone currently costs 176400 to buy (It's only recommended to use it to take the place of an item worth more than that, or you get them for free)

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)
