I got 4, this is on my 2006 MacBook Pro, calibrated with a Monaco Optix XR. All four errors are in the cyan range (blue-green crossover), so I suspect the panel can't differentiate them well due to a constricted gamut. I'll have to try it on the Mac Pro; I'm sure that will be easier due to the much larger gamut and a panel with a brand new backlight.
I don't think that it matters if your monitor is calibrated or not for this test.
The colors should still go in order regardless of calibration.
