Hi Mitch
Del Mar did seem to have faster workouts than Santa Anita is currently showing
Here is an example
First DEL MAR 2016 Maiden winners (trainers col K highlighted )
These winners ran a 92 or higher work out speed rating,( Col 0)
and also had a 5 or 6 furlong work within 9 days of the winning race
Here is the same thing but from the current SA meeting
Notice the speed ratings are so much higher at Del Mar , thn at SA (Col, P)
