Can’t wait to see what figure My Boy Jack earned. Pretty impressive finish considering trip and paths wide on turn 2.

TGJB: Best guess is he gets about what he’s been running, unless you want to go really big with the top 3. There are going to be a lot of x’s.

Flighted Iron: Sounds like you\'re in the neighborhood of neg 1ish for the winner.

TGJB: Probably a little better but I haven’t seen ground yet. Second and third horses could meet right around there.

Flighted Iron: Some time ago you mentioned having trackmen.How do you calculate ground for the derby?

TGJB: We have two different observers who do it independently, than we isolate discrepancies and review them.

Flighted Iron: The coverage on cbs is pretty darn good. I\'ve watched audible\'s trip 2 or 3 times in the last 5 minutes. Javier saved quite a bit of ground. Quite possible it\'s a 1.5/1. I know it\'s unsolicited, but with lengths beaten + ground audible is 2 pts slower than the winner.

GAM: TGJB, was wondering last week and this topic seems like a good place to ask:  with the emergence of Trakus does Thorograph utilize their data for distance ran by each horse or do you still do it the \"Old Fashioned\" way?  (Sorry in advance if this has been discussed before)

TGJB: It has, and in general we do not. We have found their stuff to be uneven, more accurate at some places than others (as one of their guys told me himself a few years ago).

Fairmount1: I assume the genesis of this question is that the Derby chart says that the margin between Solomini and Firenze Fire was 2.5 lengths when it is clear it is much, much more at the finish from photographic/video evidence.  On twitter it is being pointed out that possibly CD used Trackus for margins right now.  

There are other instances being discussed from Saturday\'s card with similar problems.

JR: Interesting trackus data

Instilled Regard - beaten ~4.5 lengths ran 20ft farther.
Bravazo - beaten ~7 lengths ran 44ft farther.

Weird things happen on sloppy tracks.
