So I'm lowering my WTA content to 15%, the plan is to eventually wean off the WTA. But I'm posting about it here because I have to overcomplicate things and I did it in a very roundabout way.
First I diluted 36 mg WTA to 24 as I've been doing. Then I mixed some 24 mg unflavored and mixed that at 25% with my 24 mg WTA, so I have 24 mg liquid that is 75% WTA. Then I mixed THAT with my v2 berry mix at 20%. It maths out to 15% WTA.
It's kinda handy to do it that way though, because it dilutes my flavoring to 80% of the original mix strength just like before. So the flavor shouldn't change.
Maybe someone will find that interesting.
