I'm glad that I'm not missing the boat.  I'm really looking forward to the 2nd Edition and the new content that it will bring.  As for categorizing the Tiers:

Total Body

Tier 1: Total Body Lifts & Oly Lifts/Variations from the Floor

Tier 2: Oly Lifts/Variations from the Hang and Upper Body Oly Lifts

Tier 3: Oly Lifts/Variations & Total Body Lifts from the Blocks and Upper Body Oly Lifts

Tier 4: DB Lifts/KB or DB Swings

Tier 5: Jumps

Lower Body

Tier 1: Free Squat Variations

Tier 2: Box Squating Variations

Tier 3: Barbell Single-Leg Exercises

Tier 4: Dumbbell Single-Leg Exercises

Tier 5: Bodyweight/Cals

Upper Body:

Tier 1: Barbell Supine Lifts & Horizontal Row Variations

Tier 2: OH Barbell Lifts & Vertical Pulls

Tier 3: Incline Lifts & Vertical/Horizontal Pull Variations

Tier 4: DB Variations & DB Row Variations

Tier 5: Bodyweight/Cals (Both Pushing and Pulling)

I've been continually revising this list so things change from time to time when I remember exercises or learn something new that I want to try.  I could be way off with the placing the exercise types in the right tiers.  Recently I've been utilizing a 3x3 tier system with added tiers 4, 5, &6 for only Posterior Chain, UB Pulling Exercises, and Bodyweight/Cals respectively.  This has allowed me to not overthink exercises too much and stick to the basics. 

So it would look like:

Day 1: Total Session

Tier 1: Total Body Lifts & Oly Lifts/Variations from the Floor

Tier 2: OH Barbell Lifts & Vertical Pulls

Tier 3: Barbell Single-Leg Exercises

Tier 4: Posterior Chain: RDL

Tier 5: UB Pull: Opposite Movement of Upper Tier 2 Combo. (Example Tier 3: DB Row, UB Pull: Chin-Up)

Tier 6: Bodyweight Cals: Box Jumps

Day 2: Upper Session

Tier 1: Barbell Supine Lifts & Horizontal Row Variations

Tier 2: Box Squating Variations

Tier 3: Oly Lifts/Variations & Total Body Lifts from the Blocks and Upper Body Oly Lifts

Tier 4: Posterior Chain: Partner Back Extension

Tier 5: UB Pull: Opposite Movement of my Upper Tier 1 Combo. (Example Tier 3: DB Row, UB Pull: Chin-Up)

Tier 6: Bodyweight Cals: Upper Body Movements (Example: Dips-n-Chins or Push-Ups-n-Chins, etc.)

Day 3: Lower Session

Tier 1: Free Squat Variations

Tier 2: Oly Lifts/Variations from the Hang and Upper Body Oly Lifts

Tier 3: Incline Lifts & Vertical/Horizontal Pull Variations

Tier 4: Posterior Chain: Eccentric Glute-Ham/Leg Curl

Tier 5: UB Pull: Opposite Movement of Upper Tier 3 Combo (Example Tier 3: DB Row, UB Pull: Chin-Up)

Tier 6: Bodyweight Cals: TRX/Blast Strap Pistols, Lunge Variations

As you can tell, without having Tiers 4&5 I'm missing volume but I try to counteract it by having the athletes perform Bodyweight/Cals.  Usually the Tier 1-3 sets/reps are: Block 0: Total: 5x3, Upper/Lower: 5x5 and for Blocks 1-3: Prilepin's Chart.  While Posterior Chain and UB Pull Tiers are 3 sets.  Bodyweight/Cals sets/reps can range from 3-6.

Essentially, I've been melding both your Tier system with Wake Forest/Ethan Reeve style workouts. 

Thanks again Coach for taking time to help me out.  Also, sorry for the long winded reply.  I'm looking forward to your response.

Thanks,

Chris Tolzman
