I re-skimmed the deadlift section of SS:BBT and ran a search but did not find the answer to this question.

Is there any guidance regarding rest/reset time in between deadlift repetitions? I'll perform 1 rep, set the bar down and reset everything before performing my next pull. This time in between reps might be anywhere from 15-30 seconds. Am I losing anything, or completely F'ing up the program by not immediately pulling again once I've returned the bar to the floor?
