You might be on to something. Pick say 20 rookies and the 10 top premiums. Leave yourself 1 to 1.2 million to spend. Then instead of needing to do rookie corrections, you can just correct the crap ones to proper premiums.
I probably won't, and instead spent $300k or something to upgrade to a fallen premium but I am wondering if sitting on it reduces the overall risk (at the severe cost of going backwards early in the year).
