Not really. It tries to measure "impact" and while direct measures like number of CLs can potentially go into that, this is definitely not the rule.

Then again, Google is best thought of as a collection of semi-independent companies loosely bound by culture. Individual managers have a lot of leeway in how they operate, and VPs and Directors have tons of control on how they run their organization, including measuring performance. There are good teams and there are not so good ones.
