I've only taken a very light look so far. If my memory is right, I think Derby winners often have a race about three weeks out. It may not be the best approach, but I usually look at the Derby on the last couple of days before the race.

Here is the "Winning" Profile for the last 4 Derby winners
1) No layoff line since the last race
2) Posts 7-7-18-20 were the last 4 winning posts
3) Beyers were 82 101 91 107 Average Beyer exiting last race was 95 so 90+ Beyers LR best
4) Either show no regression in L3 (Beyer either stays the same) or drops a few and picks back up in L3
5) 22% Average Jockey win %tage and 26% for Trainer
6) Last race prep track horse has already had 1 start on that track prior to LR
7) Shows outside post in LR prep (6/8 8/11 and 6/7 were shown from L4 winners)
8) Shows being the favorite in at least 1 of the L3 races
9) Born in the month of either march or may
10) Shows at least 1 start in the "Wet"
11) Shows 1 part of the race not moving positions (Ex 33 44 55 etc)
12) Either is Bay or Chestnut color
13) Sire Stud Fee Over $20k
14) Has at least 1 horse in today's field that has raced with him/her prior to today
15) Average TF Early 100 Late 91
16) Average Odds on morning-line 14-1 (County House was 30-1 so it skews the data)
17) Trainer has at least 1 stat over 20% (does not matter for stat but GrdStk was 24% Avg)
18) Shows at least 1 workout after LR with a workout over or at 5 Furlongs
19) Trainer/Jockey combo is over 25%Year not track (26% was the Average)
20) Shows going wide in at least 1 of the L3 races
21) Winner was bred in Kentucky
22) Shows a Career BB of at least over 90 (Average was 99)
23) Shows Career earnings of over $300k (Average was $575k)
24)Shows at least 1 weight change in L3 races
25) Shows at least 1 Itm finish L3 races

There is probably more that I missed but there are at least 25 different angles for the Last 4 winners and yes I did count Mandaloun as being the 2021 Derby winner for stats purposes :)

Thanks, Conley. Very interesting.

Lol- Conley you are the best!! I love those types of stats although IMO they are not reliable. I remember being touted on a college hoops game once where team A had not lost a road game in an arena whose capacity was less than 15,000 in several years. Well the stat held up as team A won once again.
I prefer angles that match up todays entrants. Such as the last 4 derby winners ranked 1-4 on LP.
Nevertheless I love reading these types of lists. I've had a very bad last 2 days being sick and this list certainly brought back some memories and made me smile

Hopefully there are a few gems among what Conley put together.

For no valid reason, it does bring to mind the sort of thing a local radio guy would say. When this team comes off a win and plays on Monday in an east coast city against a team that has lost two in a row and has not won a Monday game in 4 years... you get the idea. lol

In case I was not clear, I am not in any way trying to be critical of Conley. He put in a lot of work on those stats and I think they are well worth careful consideration. And, as Tony said, certainly a great read.
