Here is a sneak preview of the ATP errors made in the Year-End rankings of 1973, with the top 50 positions mentioned in World of Tennis 74:
FACTS AND ATP ERRORS:
1. You will notice Newcombe's target failing by 6p he gets from Palmetto (so this is not an error).
2. Stan Smith is missing .5p, but this may be a missing tournament we have not found yet. Fact is that Smith was .5p in the reproduced list of the Aug 23 rankings as well.
3. Pilic's official tournament count is 28, I am getting 27.
4. Riessen had 61p in the Aug 23 rankings, 4p more than what I was getting. This is an ATP error, as he didn't seem to miss anything.
5. Fillol, Gottfried and Cox all have something in common. They are 3p short from their official total. I am gonna go with the Riessen here as well, and call this an ATP error, as there is no tournament class that can be modified in common for all 3 not affecting anyone else.
6. Bertolucci is 1 tournament too far from the official count. This is another ATP error, and there is also a typo in the World of Tennis '74 book.
7. Drysdale's and Fairlie's tournament count totals are wrong. Drysdale played 2 more tournaments than the official total. 2 more ATP errors to add.
8. Stockton's lack of 4p is perfectly valid with a missing Palmetto final, tournament missing from the ATP's database.
9. Dibbs is just .5p too short than the official count. This is an ATP error caused by miscounting a CAT-D tournament's R32 as a R16, spawning 1p instead of .5p.
10. Meiler's and Van Dillen's tournament total is incorrect. But Meiler's extra tournament is a CAT-F final, which ATP failed to count, hence his 43.5 instead of 39.5, placing him higher in the rankings.
11. Parun is just .5 point short to the official. This is another ATP error caused by miscounting a CAT-D tournament's R32 as a R16, spawning 1p instead of .5p.
12. Pasarell's missing 4p, probably caused by miscounting one of his multiple tournaments spawning 4p as a 0p. (late disqualification?)
13. Proisy's missing tournament and point are caused by the ATP failing count his Barcelona's event in spring.
14. Fassbender's .5 point too short. Caused by ATP miscounting Nice as 0p, instead of .5p.
15. Graebner 2p too short and 1 tournament too short. Once again, Palmetto solves this, since Graebner got SF here, gaining 2p, solving both these errors.
So, taking out the light green errors (which are ours, not ATP's) we have a few ATP errors remaining, but we also have 100% loyalty.
