ADXL357 self test results

Hi,

I have technical question again regarding the ADXL357 self test mode because there's not much info about it.

I have enabled the self test mode by writing 0x03 to its self test register (0x2E) and read its Z-axis output.

 

Below is the test result from our previous PCBA build for 9 sets of ADXL357.

Comparing the above result with the datasheet specification, can I say that only 2 out of 9 are passed the test? 

Or is there something else that I have missed out during setting up the device prior for self test mode.
