"Deep Staging" is the name of John D's column in the magazine. It has nothing to do with the content of the editorial, which is time management.
At Loose Rocker Promotions, we pride ourselves on time management. The two biggest factors are 1) having cars in the lanes and 2) time between the burnout box and the starting line. We have finished a race with 416 entries, 1 time trial, 1 round of re-entry style buybacks in just over 14 hours, including having dragsters, double-entries, late-round cooldown, talking splits, and any breakage, track prep, or other downtime, etc.
Big props to Jeff Stout! That's how you do it!
