DRF - Workout or typo?
 

I've never seen this in a workout line, but there is another horse in the same race with one. After the Breeze indicator (B) there is what appears to be a pair of "S"s stacked on top of each other:



any ideas what this means?

The only thing that would make any iota of sense is 'standing start' -- it's either that or a typo.

Virtually all works are either from a gate (lowercase g obviously), or breaking off at a pole. Not sure it means that, but what else could it mean?

Yeah, but wouldn't the drill be slower than only 2 sec based on the 6/8 work?

I might guess "Side by Side" if working in company throughout. Or, if a gate work "Stumbling Start" or "Slow Start", but never seen that noted for a work line. Interested to find out. Nice Catch.
After watching some of the Tampa Horses in person over the years...it could mean "Should Stop" Racing. :)

It is 2/5 to be a typo.

I'll take NO typo

Guessing sealed track - I've seen this before, just forgot what it was

The track was labeled fast in the workout.

The symbol is in a spot that is either left blank, or filled with a lowercase 'g' indicating a workout from the gate. It most likely means nothing.

Super Slow.
