Your Readiness Rating is one of the most integral components to customizing your program. The Readiness Rating is based on research and development of a proprietary algorithm that takes into account your sleep, motivation, soreness, performance and more to help adjust your program at many levels including pre-training, intra-training, session to session, week to week, block to block and program to program. It is critical that you are as forthright as possible when answering each questionnaire to help ensure that these ratings are as reflective as possible of you.
Scores range from around 0 to ~30
If you're consistently higher than 20 but feeling fatigued or lower than 12 and feeling great then you may not be honestly reporting your readiness questionnaire, RPEs, or end of session score
If you're consistently at or lower than 15 then consider strategies to improve recovery
If you're consistently at or higher than 20 after your second block (i.e. the system has re-calibrated your full lifter profile) then review your RPEs ratings and maxes as they may be too light. If you simply want easier workouts then stay as you are.
If you're below 10 you are likely heavily fatigued and should consider taking a break from hard training. Switching to a bridge block is perfect for this.
Your readiness decreasing through the weeks is expected but should return to around normal range towards the end of your deload and probably the first few days of your new block
