Does scoring really have to be that objective to be effective? Look at IMDB's Top 250 Movies, the polls aren't filled with opinions of skilled or experienced movie reviewers, but ordinary folk who have seen the movie and want to quantify their experience in some sort of tangible way. Does it have to be relative to other movies they've seen for it to be a fairly accurate indication of the general appeal or otherwise of a movie?
For similar reasons, I primarily use the Malt Maniacs Matrix
for getting a general overview of an expression. I can see the cumulative score and what the highest/lowest rating is. If the average of 12 people is a score in the high 80's to low 90's, I'm pretty sure that the whisky has something going on.
If you have the wallet to support the random, blindfolded, spinning and pointing method of choosing whisky, then you are a lucky sod. But as a 'normal' consumer, I want to be as informed as I can be when going into a shop with an urge to buy something.
