Workout notations

[Bill V.]

Hello Ted

Happy new year !!

Ted, I want to make sure of this notation. It is rare here at Santa Anita
but I see it now and then.

Does the SCW2 notation mean that the horse has 2 workouts faster than the workout prior to the last race?

If so is an SCW1 mean 1 workout faster than the workout before the last race. and the more rare SCW3 mean 3 workouts?

Here is an example

Thank you
