If I haven't said so already, welcome aboard,
@forkmantis.
FWIW - and I'm interested to hear if others agree with me on this point - in terms of effort and explosiveness on a scale of 1 to 10, Q&D means 10 while S&S means 7 or 8. That's a profound difference in what you're doing, so things like rest periods will necessarily be different.
I had occasion to experience this first-hand just yesterday - I had a planned S&S type session, sets of 10 swings. But I did them at level 10, not 7 or 8, and I was gassed after 4 sets and had to stop.
