Which you have actually had a chance to use on the actual beer which we are actually discussing now? Who's the true believer here? You're nothing but biased and are obviously continuously just trying to push your own agenda.
So experimental analysis has no ability to be predictive?
Follow me here, okay? Take a pencil or other nearby solid object in your hand. Hold it out at arms length. Let go of it.
Did you do it?
OKay, so while I am not at your location and did not witness the event, I can say with a HIGH degree of certainty that the pencil or other object fell straight down to the floor at a rate very close to 32.2 feet per second squared.
Again, I'm not there and didn't witness it, but I can make the (likely very accurate) assumption of what happened based on the following:
A: personal experience, repeated to the point of reliable predictability
B: The scientific measurements and conclusions of others even smarter than me which tell me the same thing
So it is POSSIBLE that you got a different result when you dropped your pencil, but I doubt it.
Do you see the power of reliable predictability?
That exact same methodology is how (within the limitations of the information provided) Die Beerery is able to predict what happened with the beer in question.
