Yep, I've got one of those, didn't think of using it for that, good idea!

Is there anywhere else to download this as a non-zip file? Or just a place to view it online?

I'm having trouble calculating what ratio of tincture to use to the decoction.
The values I'm putting in are giving me figures that don't make sense... if someone can check my calcs and maybe just humour me as I work through this I'd really appreciate it! 
OK - I have approx 2000ml of Chaga extracted in 37.5% (70 Proof) alcohol. Chaga is strained out. I'm ready to do the decoction, so I believe that I will need to begin with the same volume of water (2000ml) to match potencies of the solutions, then reduce down to the right volume so that the final ABV is 30%
Now, putting it in the caluclator, it suggests that with 2000ml of (strained) tincture, I will need to add a volume of water/decoction (once extracted, reduced, and strained) at around 500ml.
Is that right?
Start decoction with 2000ml water, then reduce down to 500ml and add to the tincture .. and that will give an ABV of 30%?
Somehow my brain won't accept it and am just posting here to get confirmation that the final ABV will be 30% AND that I am still mixing a similar potency of tincture/decoction?
It's been a long day!

You state 2000ml of Chaga extracted in 70 proof alcohol -- THAT is just liquid correct?
That means your 2000ml is composed of (2000 * .35 = 700ml alcohol and 1300ml water.)
If you want to end up with a final double extraction tincture of 30% or 60 proof -- you need to do an alcohol extraction with a higher proof alcohol.
Using your numbers -- you want a final double extraction tincture to be 30% or 60 proof.
So take the REAL alcohol you have from your extraction (700ml) and calculate total volume for a 30% (60 proof) mix
700 / .3 = 2333ml. Now subtract out of that your real alcohol leaving water.
2333 - 700 = 1533ml.
Remember - you already have 1300ml of water in you alcohol extraction so you have to reduce your water extraction liquid down to (1533 - 1300 = 233ml).
So -- you take your existing 2000ml of liquid from your 70 proof alcohol extraction -- add in 233ml of liquid from your water extraction and you will have a total volume of 2233ml at 30% or 60 proof.
Sanity check ... 700 real alcohol / 2233 (total liquid) = 31%.
Hope that helps.

That does help, thanks @Migrane
I think I'm still confused!
The 2000ml chaga extract is JUST the alcohol left after I have soaked and strained the chaga material out (At apx 200g Chaga/1 Litre Alcohol) - no water added yet. The original bottled vodka abv is 37.5%
I'm asking what volume of water I need to reduce the decoction down to to get the maximum concentration of water soluble constituents in ratio so the abv is 30%.
But, when you say this:
"So -- you take your existing 2000ml of liquid from your 70 proof alcohol extraction -- add in 233ml of liquid from your water extraction and you will have a total volume of 2233ml at 30% or 60 proof."
It sounds a lot more sensible. So in essence I have to put 2000ml of water on the chaga material, reduce down to apx 233ml, then combine. Yes?
It's setting in, slowly!

You may be able to use less that 2000ml of water to perform your water extraction with -- but in the end, no matter how much water you use -- you only want 233ml left.

I understand...eventually! Worked it through few times now and I'm happy to proceed.
Thanks @Migrane, really appreciate it.
