Showerthought: I ran the same part 3 times with the spindle warm up on and off, wild result

Ran a batch of aluminum brackets Tuesday morning cold, no warm up cycle, and the first 4 parts came out .003 oversize on the bore. Kicked on the 15 minute spindle warm up after that and the next 20 held dead on, so now I'm wondering if I've been blaming my tool offsets for nothing. Anybody else track warm up cycles against their first part scrap rate?
