So maybe you personally have improved on Crossfit in your box and are offering quality training but that's different than the baseline Crossfit-approved product that a walk-in can expect.
Then you don't know much about training the Olympic lifts or power movements in general. Take a look at this graph -- http://i.imgur.com/vFP0D58.png -- from Practical Programming for Strength Training (Rippetoe, Kilgore, & Pendlay, pg. 131). "Figure 5-3. Electromyogram (EMG) and force production tracings from a high-rep set. Note that the muscle fatigues as more repetitions are completed and that motor control erodes with fatigue, as evidenced by the amplitude scatter of the EMG tracing. This effect can result from a single set, as presented here, or can be the cumulative result of repeated sets." Even by the seventh rep of a single set there's a noticable breakdown shown in the graph. Multiple high rep sets are going to show more and more issues of coordination from even the first rep, especially mixed into circuit training with other high intensity exercises like you'll find in Crossfit WODs.
