[Property] avgPctUsageMin [Default Value] .70 [Description] 
Triggers a "shrink" when "avgPctUsage" < avgPctUsageMin/growthFactor. The difference between avgPctUsageMax and avgPctUsageMin could be thought of as another safety buffer; the larger it is, the less likely you'll have "twitchy" resizings as usage fluctuates (imagine min and max were the same, and the avgPctUsage were fluctuating around that number)
