Rest times by the guy who wrote that article
"As for rest, this is a PL routine, so the answer is alway the same - as much time as it takes to fully recover between sets. 5 minutes would be a good average for me, but the higher volume sets take longer. With 4 9s I rested 10 minutes between the 3rd and 4th set. On 10 3s day, I only had to rest about 3 minutes between most sets, but that increased as the weight went up and toward the last few sets. Do it by feel, and avoid the pump at all costs!
he is right, having a pump in the legs ruins the quality of the sets
