Uncoupled entry same owner and trainer?

[Lost Cause]

Hey Everyone,
In tomorrow\'s first race at aqu Jacobson is the listed trainer of three horses and all show him as either owner or part owner.  The problem is only two of the three are coupled why would the thrid not be coupled.  I must have missed a rule change.  Anybody know?

Heard that there\'s some percent of ownership cutoff, where they don\'t couple.

 It\'s not easy enough for them to gain an edge, we need this too.
