ADXL327 perpendicularity between axis

Hi all. ADXL327 analog acelerometer datasheets reports a typical misalignment of every axis in the order of ±0.1º.

From this data, I understand that the angle between two axis should be 90±0.2º.

Recently, we have performed an accurate calibration of one unit of this accelerometer, belonging to the Part Number #1025.

The results we obtained show that there is an angle of 91.2º between X and Y axis, but this result contradicts the datasheet, at least the way in which I understand it.

My question is: is it possible to have this lack of perpendicularity between X and Y axis? Am I misunderstanding the datasheet?

 

Thanks in advance,
