Well put. Evaluating "CrossFit" is difficult by design---HQ wants boxes to be almost completely autonomous. The best statement of CrossFit's philosophy is Greg Glassman's "World-Class Fitness in 100 Words"[1]. There's nothing there about doing lots of poor quality reps as quickly as possible.
I began my CrossFit career at San Francisco CrossFit and thought it was the best thing ever. Part of each session focused on mobility. Bad reps were not tolerated. It was like a daily seminar on how to maintain, tune, and fix the human machine. The skills I learned will benefit me greatly as I age.
Then I had to move, and I saw the dark side of CrossFit. Inept trainers with poor attitudes, encouraging speed and weight with no concern for proper body mechanics. I work out on my own now, practicing skills I learned at SFCF.
Bottom line: it's the box that matters.
[1] "Eat meat and vegetables, nuts and seeds, some fruit, little starch and no sugar. Keep intake to levels that will support exercise but not body fat. Practice and train major lifts: Deadlift, clean, squat, presses, C&J, and snatch. Similarly, master the basics of gymnastics: pull-ups, dips, rope climb, push-ups, sit-ups, presses to handstand, pirouettes, flips, splits, and holds. Bike, run, swim, row, etc, hard and fast. Five or six days per week mix these elements in as many combinations and patterns as creativity will allow. Routine is the enemy. Keep workouts short and intense. Regularly learn and play new sports.
