Decarboxylation losses to figure in?

[OlderNOTwiser]

I've not yet done a tincture but I'm doing the background stuff in anticipation. In this video around 1:45 there is a formula that uses .88 as a multiplier for losses due to decarb. While it does make sense that some losses may occur I've never seen it spelled out or quantified like this. This video is about cooking and not soaked or aged very long so not likely real strong but it is the .88 that gets me. I have been doing high CBD capsules for a while now and never considered the loss in formulating strength and/or dose. Is this actually an important point (if so why hasn't it been pushed harder? Or did I simply miss it?) In my capsules it is almost a rounding error but when combined with making a tincture at 70 - 80% it adds up. What about ABV flower? Is there a factor to be used here that is different from the decarb factor?

Do you seasoned veterans figure it into your calculations?

I have made tincture once. I used the Ed Rosenthal method as outlined in the GWE website. I used 151 rum instead of Everclear. It works rather well but tastes terrible. We tend to mix it into a drink. I believe I used .50 oz. of scrap +.25 oz. of bud. It takes about 3 dropperfuls (from a 1 oz. bottle) to make rainbows shine with bluebirds and unicorns fluttering about. Production was five ounces. I provide all of this as a preface to answering your question.

I truly don't believe this is a real exact science, unless you have visions of becoming a producer. I followed the directions, adjusted the formula to my needs and achieved results. Next Time I will use Everclear.

I decarb in a turkey roasting bag. You can get a box of 25 pretty cheap online.
It also helps some with smell, if that is a concern.

My go to for decarb is the Ardent decarboxylation chart. For tincture, I learned all I know from "Another tincture thread" by Psychedelic Sam. You'll have to google these OlderNOTwiser because I don't have a go to for how to post a link. The Ardent chart will address your loss equation. As far as using ABV, without a lab test it would be difficult to ascertain the remaining THC available for your tincture dosing.

quirk mentioned the tincture work of Psam that was extended by ReikoX at Overgrow.com. Here's a link to that authoritative thread. Worth checking out.

Then after the decarbox what are the losses for example when making canna butter? I found that when I made some chocolate using melts and canna butter some of the chockies were stronger than others. I gave the butter a good mix in the melted chocolate so I dont know what caused the difference in strengths between individuals after being portioned out into teaspoon size choc buds.
