A couple things to remember:

1. Grey cards aren't always neutral. The Kodak ones in particular are
somewhat warm.

2. Your meter is calibrated for approximately 12.5% grey (ISO
standard). Cards are calibrated to 18% grey (Kodak's choice at Ansel
Adams suggestion). Thus grey cards do not actually function as
described but rather cause a slight overexposure .
