Self test output change limits vs supply voltage

Hi , 

I would like to know with regards to  Self-Test Output Change Limits vs. Supply Voltage for ADXL345 and ADXL343 . 

The measured min and max for self test values are given for Vss = 2.0 and VDD/IO =1.8V . 

We are planning to use in Vss = 3.0 and Vdd/IO=3.0 .

Data sheet states  For other voltages, the minimum and maximum self-test output values should be adjusted based on (multiplied by) the scale factors shown in Table 14.

I would like to know if the scale factor valid to all VDD/IO = 1.8 to  Vss.

Thanking you 

With best regards
