High Point Computer Company recently bought the Compact Computer Company. They both make $1,000,000$ units per year of very similar desktop computers in their plants in California and Texas, respectively. At a meeting of the VPs for operations one year after the merger, both sides claimed that their plants had made bigger improvements. As evidence they presented the following information:

High Point $($Calif$)$: Inventory was moving last year at $25$ turns per year but this year it moved at $40$ turns per year.

Compact $($Texas$)$: Average inventory at the same time last year was $40,000$ whereas this month it was only $25,000$ computers.
