I understand that completely, much like hot sauce, one person's medium, is another person's hot, and yet someone else's mild.
But the sauce is the sauce, calling it hot, or mild doesn't change what it is, or how it is perceived.
Maybe I should leave this alone, but I am just trying to understand.
Obviously software can't 100% accurately predict actual IBU's, but it will be close enough for our purposes.
It just seems odd to me that if you like a 50 IBU beer, why would you change the utilization to call it a 70 IBU beer, or a 30 IBU beer.
Isn't the scale, the scale, and what is different is our perception of bitterness?
