USGA Purchasing Drivers For Testing!?

On the Nike Sumo2 driver mess, Gene Yasuda slips this in his Golfweek.com story:

According to Nike officials, a competing manufacturer contacted the USGA and urged it to test the new Nike driver on suspicion that the Sumo2 was "hot." Upon inspection of drivers purchased from four retail shops in the New York-New Jersey area, USGA officials confirmed that some of them exceeded the CT (Characteristic Time) limit – a measurement that determines spring-like effect. Nike was notified in late February.

They had to buy four of those things? No wonder they have to cut employee benefits!
