1st place  @TC33

2nd place @TheGeneral

3rd place  is a tie between @Withering Wind and @silverseeker

There will be a tiebreaker round to determine the 3rd place winner. I'll put that together, and provide a link in this thread and the round 4 thread.

[grendelbo]

Congratulations @TC33!

[CGC Mike]

Here's a link to the tiebreaker round for 3rd place.

Congrats TC and General! well done!

[Superman2006]

Congrats to TC33 and the other top finishers!

I finished one point out of a top 10 finish, ending my continuous streak of top 10 finishes dating back to the 2nd contest (I didn't join the first one). The competition is getting tougher!

[CJ Design]

I was doing okay until 3..then it was my worst ever...I'm still punishing myself...I think I may like it. 😱😈😉

[JollyComics]

Congrats to @TC33 for having amazing last two rounds to atop of the contest.  A big hat off to @TheGeneral for 2022 Summer Grading Contest Winner and 2023 Winter Grading Contest Runner-up.

Wished a good luck to @Withering Wind and @silverseeker for 3rd place.

So far, 93 contenders completed all four rounds. Congrats to all with great effort.

According to Mike's grade distribution table, only 92 players completed Round 4 (down from 114 at sign-up, 107 in Round 1, 101 in Round 2, and 99 in Round 3).  Here are the key measures of central tendency for this round (Mean = the average grade; Median = the middle grade in a numerically rank-ordered list; Mode = the most common grade):

Book	CGC	Grade Distribution Statistics
#	Grade	Mean	Median	Mode
16	3.0	2.3	2.0	2.0
17	5.0	5.2	5.0	5.0
18	7.0	7.4	7.5	7.5
19	5.0	5.3	5.0	5.0
20	9.4	9.3	9.4	9.4

The Board scored 124 bulls-eyes in Round 4 (27% of all grades submitted, compared to an average of 20% in 2022 Grading Contests #1 thru 4).    Here are a few other notable observations based on the data reported above:

• Book #16 (Startling Comics #40):  The toughest book for the Board as a whole, with only 12% of the contestants at the same grade as CGC and only 43% within one grade increment of CGC.  Collectively, the Board was about one and one-half grade increments more critical than CGC (2.3 vs 3.0).     
• Book #17 (Strange Confessions #1):  A relatively easy book for the Board as a whole, with 29% of the contestants at the same grade as CGC and 67% within one grade increment of CGC.  Collectively, the Board was about one-half grade increment more lenient than CGC (5.2 vs 5.0).
• Book #18 (Fantastic Four #50):  Another relatively easy book for the Board as a whole, with 21% of the contestants at the same grade as CGC and 65% within one grade increment of CGC.  But this time, the Board was nearly one grade increment more lenient than CGC (7.4 vs 7.0). 
• Book #19 (Batman #210):  Yet another relatively easy book for the Board as a whole, with 26% of the contestants at the same grade as CGC and 60% within one grade increment of CGC.  Collectively, the Board was about one-half grade increment more lenient than CGC (5.3 vs 5.0).
• Book #20 (Captain Marvel #31):  The easiest book for the Board as a whole, with 47% of the contestants at the same grade as CGC and 77% within one grade increment of CGC.    Collectively, the Board was about one-half grade increment more critical than CGC (9.3 vs 9.4).

Kudos to Mike for yet another well-run contest.      Congratulations to the victors ( ) and condolences to the vanquished ( ).

To the reinvigorated in next contest ().

[flashlites]

Congratulations to the top 4!!! Can't wait to see the tiebreaker round!

[divad]

20 zzutak - that's an average of 1 grade off each book - not too shabby!  After reviewing the roster . . . that's some mighty stiff competition!

  Thanks for all your hard work, time & effort to put this together Mike!  Wow, that was fun, I wish I had entered all the prior grading contests! 

 

[sledgehammer]

20 points last time had me in a tie for 4th.

Some great scores this time, by the same old names.

Clearly, @Squirrel Guy, was no fluke.  I think he had a similar very low score when he won.

@zzutakposted this in another contest. I always found it insightful. I hope he doesn't mind me sharing it again.

 

I've posted this before, but I think it's worthwhile to share it again.

Back in the mid-2000s, Ed Jaster (who had recently joined Heritage Auctions) told me the "trick" to having your books certified by CGC was to max out your invoices rather than submit only a few books.  "Sometimes you'll be higher than CGC, and sometimes you'll be lower; but if you're a decent grader, your average grade should come pretty close to CGC's."

CGC's proprietary (and still unpublished) grading rubric necessarily allows for judgment, and different graders may interpret/apply a given standard differently.  Blemishes/defects can be overlooked or discounted for any number of reasons.  The bottom line is that a given book may not always receive the same CGC grade if it's submitted several times (although the various grades assigned will almost certainly be within an increment or two of each other).  This fact (not opinion) will be obvious to anyone who's done an initial prescreen and then had the rejected books accepted on a later, identical, prescreen.  This is not meant to be a slam against CGC; I know of no collector who can/will assign the exact same grade to every one of his/her books every time he/she looks at 'em.

 So, just for kicks, recalculate your total Contest #3 score using "signed deltas": -2 for your guess being 2 grade increments too low, -1 for your guess being 1 grade increment too low, 0 for a bullseye, +1 for your guess being 1 grade increment too high, +2 for your guess being 2 grade increments too high, and so on.  What's your cumulative 20-book tally now?  Did the errors to the low side and high side more or less balance out?  Or is your tally way negative or way positive (in which case you're consistently being too strict or too lenient with your condition assessments)?

 Chances are your score using signed deltas will be much smaller than your score using absolute/unsigned deltas.  If that's the case, your errors are balancing out (which is exactly what Ed predicted would happen for a decent grader).  Here's an example using my own Round 1+2+3+4 guesses (20 books):

        5 Bullseyes = 0
    
        3 times my guess was one grade increment too low = -3
    
        7 times my guess was one grade increment too high = +7    
    
        3 times my guess was two grade increments too low = -6  
    
        2 times my guess was two grade increments too high = +4

My total signed delta score would be 0 - 3 + 7 - 6 + 4 = +2 for the 20-book challenge.  That's an average error of one-tenth of one grade increment (0.1).    Compare that to my total absolute/unsigned delta score (my actual contest score) of 20, or an average error of one grade increment per book.  This is exactly what Ed Jaster predicted would happen for a person whose grading standards are essentially in line with CGC's.

Until next time!
