Exact max experimentation percentage

[code9]

Hey there. So I'm working on crafting a Droid Engineer module that has a value ranged 1-20. I can get it to 19 with my materials on hand, which of the three mats two of them are server best for this schematic. I'm trying to figure out if bumping the third material to server best (which I can buy but is pretty expensive) will be enough to push me over the top to get that item to 20.

So first off I did some experiments. Right now with my best materials I get the experimentation meter to 95%. This coincides nicely with the idea that on a 1-20 item every five percentage points would translate to 1 point on the item. So far so good. Then I did some test and found that at 93% I still get a 19 point item, but at 92% I get an 18 point item. Ok, so it rounds to the nearest 5% with regards to my item. That means to get a 20 point item I would need to hit 98%.

My question then is there a way to pre-calculate exactly how much of a bump a material would get me? For this schematic it uses:

55 Steel
50 Copper
20 Inert Gas

I'm trying to see how much this all directly affects the quality, espeically since the gas is the mat I'm looking to upgrade. Does the amount of material used impact how much wight that has in the final product? For example is the equation something like....

(55/125) * (Steel Quality Value) + (50/125) * (Copper Quality Value) + (20/125) * (Gas Quality Value)

But it doesn't seem to be that straightforward, as I tried out this formula with some lesser materials. For the quality values I used (CD + OQ) / 2, since the schematic states 50% OQ and 50% CD. Since gas has no CD I calculated it two different ways, one just using the OQ number and once using (OQ + 1000) / 2. In the end my calculations came out to 49.9 for the first way of calculating the gas value and 55% for the second way of calculating the gas value. However in the game when I experimented with this set I got a final experimented value of 52%.

Does anyone know the exact was these things are calculated? It would be nice if I could pre-calculate if switching out the gas would get me to the experimental valu I want to be at to get that last point. Thanks!
