Blind Guess Accuracy

I've decided to start tracking my success rate on guessing the dram in blind pours for kicks. With my 2021 Advent calendar around the corner I thought I'd post my success rate for the prior two years and then sum up this year's after completion. Correct guess is 1/1, and I'll count non-specific guesses as a decimal with reasoning provided for each score. Here's the breakdown:

• Advent 2019*
1. Correct on Octomore and edition, but not release: 0.5
2. Total whiff: 0
3. Correct distillery, ABV range, peatedness and cask type: 0.75
4. Correct distillery and age range: 0.5
5. Only correct about the peat: 0.1
6. Correct distillery, casks involved, and age range: 0.75
7. Correct distillery and IB, but not specific bottler: 0.5
8. Correct but deduction due to lack of conviction: 0.9
9. Nailed it: 1
10. Pretty much only guessed the peat: 0.1
11. Got the cask type right, but missed on the brand: 0.25
12. Not really close at all: 0
13. Correct distillery, but way off on the rest: .25
14. Correct distillery kind of, and right about not core: 0.75
15. Correct distillery: 0.25
16. Correct distillery and cask: 0.75
17. Ditto: 0.75
18. Correct but slightly non-specific: 1
19. Wrong: 0
20. Right: 1
21. Correct distillery: 0.25
22. Correct: 1
23. Correct: 1
24. Correct, but I knew it was the only option: 0.5
• Total: 12.6/24 (12.1/23 if you don't count the field of 1 guess)

• Advent 2020
1. Correct distillery age age: 0.5
2. Correct about blend an confused by all elements: 0.5
3. Nope: 0
4. Correct bottler: 0.25
5. Correct distillery, ABV, cask, and age range: 0.75
6. Correct distillery and bottler: 0.75
7. Correct distillery and bottler: 0.5
8. Not very close: 0
9. Correct: 1
10. Correct age range and distiller-ish: 0.5
11. Correct distillery but wrong casks: 0.5
12. Correct, but compromised: 0.1
13. Just a bit outside: 0
14. Not even a hit on one of the options: 0
15. Correct distillery: 0.25
16. Hit on a cask and sort of got the distillery: 0.25
17. Nope: 0

24. Not quite: 0
• Total: 6.9/24

*This was from a selection of 24 samples so while I didn't reference a list, I at least vaguely knew what samples were in the pool, and of course the 24th guess could only have been one thing.
