This comment is not aimed at you, Hwk-I, but rather is just a continuation of the discussion from my own perspective, as I think it is good discussion (and hope that others think so too)...
I have thousands of beers scored in Untappd. I have given 5's to dozens of them. On such a small scale, well why not. I wish the world was full of 5's. It's not, but if a beer is really world-class with zero flaws, then that's how I score it. It deserves the recognition. Same can be said for 1's and 2's as well of course, dozens of those too unfortunately. I figure, if we're going to give a range of 1 to 5, or 13 to 50, or whatever, then the full range is intended to be used, not just the middle. Not every beer is just a 3 or a 30 plus or minus a fraction of a point. I am all about normalized distribution of data. I like math, too, so I guess to me it just makes good sense to use the entire range as it is intended, not just start in the middle and work up or down by tiny amounts. By spreading it out I feel I have a better sense of truly how great or how horrible a beer really is, relative to all others. I think a lot of judges aim for the center then add or deduct points from there. But I don't really agree with that method. Starting in the middle might be okay, IF you also challenge yourself to consider whether your 30 is really a 35 or a 25. Or is your 3 really a 3.5 or a 2.5. Or whatever. Use the whole range. Everything is not mediocre. Many beers are mediocre, yes. But sometimes there is an aspect or two that stands out for one reason or another, good or bad. Don't be afraid to spread the scores out a bit so they better characterize what you really taste, rewards or dings for good and bad.
I know I'm just talking in circles now so I might just duck out for a while. Cheers all.
