Hinshaw Rowing Workout - SR b/t?

[maybelle]

I’m just starting some Hinshaw rowing workouts and he references “SR b/t” - does anyone know what this means? I assume b/t just means “between” but I can’t make out the SR part.

For more context it reads like this

“150M at fast pace or SR b/t 32-36
100M at moderate pace or SR b/t 28-32”

Thanks for any help!
