Low back pain template

Hello. I just purchased the low back pain template and am a bit confused on the 3-0-0 tempo. Does this mean 3 seconds on the eccentric phase 0 seconds at the bottom and 0 seconds for concentric?

Also, for the Rehab Exercise 1 (flexion) the exact same list of exercises are listed for Rehab Exercise 2 (Extension). Which exercises are for flexion and which are for extension? They can’t both be the same can they? For reference I have template version 2.1

Yes, that means 3 seconds on the eccentric then no pause at the bottom and a normal paced concentric.

On the template, the flexion options for phase one should be different iterations of sit ups while extensions are supermans, back extensions, and cobras. For phase two, the flexion exercises are the same but there is more emphasis on the primary lifts with the rehab exercises taking more of a back seat. For the extension exercises the list we have is a glute ham raise, superman, back extension, good morning, or hip extension. I am not seeing where flexion and extension are the same.
