Update: April 10/11th
Ok...input material no longer matters, but earthworm purity is now essential.
I do not have any numbers on this yet. Contributions requested!
Update: April 9th
Purity Trees will soon be ready for chopping. When they are, Purity Compost Bins can be created and the other half of the formula can be tested: Does Compost Bin purity get a diminishing modifier too, or just Humus?
Check Post #12 for instructions.
Update: April 4th
Rough formula: Out = ( (Inp/Mi) + Cb) / (1 + 1/Mi)
Inp = Input material's elemental compostion
Mi = Input material's Purity Multiplier
Cb = Compost Bin's elemental composition (All pre-update bins should be 25.00 across the board)
What this formula MEANS is that you take a weighted average of Compost purity and Bin purity, with the "weight" being the inverse of the purity.
To put it simply: More pure things have less "weight".
Still unknown:
-Why is there a minor but consistent error with this formula? It's good for the first two digits (the ones that matter), but the first decimal place is usually off.
-What effect will Purity-Bins have? Will higher bin purity reduce its relative weight?

Humus purity is now affected by Compost Bin purity: viewtopic.php?f=2&t=5685
Ok, here is what I need: Look into your compost bins at the elemental composition of the compost which was produced BEFORE the latest update, and the stuff produced AFTER.
In each bin, write down the Elemental Composition of the Old-Humus and that of the New Humus, and post them here.
Format: Salt / Merc / Sulf / Lead (use all 4 available digits. "25.00", not "25")
Data now, analysis later.
You don't have to be colorful like me, and screencaps will be fine too. We just need the numbers now while they are easy to get. When else will the comparison between Input and Output purity be so easy to measure?
I have 6 Compost Bins:
Bin #1a
24.35 / 25.53 / 24.84 / 25.28 - Old 1.00
24.68 / 25.26 / 24.92 / 25.13 - New 1.00
Bin #1b
24.36 / 25.53 / 24.83 / 25.28 - Old 1.00
24.68 / 25.26 / 24.92 / 25.14 - New 1.00
Bin #2a
25.34 / 30.82 / 22.59 / 21.25 - Old 1.06
25.16 / 27.81 / 23.84 / 23.19 - New 1.02
Bin #2b
25.31 / 30.72 / 22.65 / 21.33 - Old 1.06
25.15 / 27.76 / 23.87 / 23.23 - New 1.02
Bin #3
26.36 / 26.06 / 26.03 / 21.54 - Old 1.02
25.67 / 25.52 / 25.50 / 23.29 - New 1.00
Bin #4
17.97 / 44.25 / 19.92 / 17.87 - Old 1.60
22.36 / 32.23 / 23.09 / 22.33 - New 1.08
Preliminary analysis shows that it is NOT a linear recombination.
The Bin and Feed purities are not simply being averaged; something a little more complex is at work.
*****
Update: Include Purity-Multiplier for each kind of Humus.
I suspect it's
(Bin * (Feedstock_Purity_Multiplier) + Feedstock)
1 + Feedstock Purity Multiplier
Or, for an example for mercury in Bin#4:
(25.00 * 1.60) + 44.25 = 32.40
(1 + 1.60)
The new Mercury value is actually 32.23, but I think that's within the margin of error for the multiplication factor only showing 3 digits.
