ADXL 312 FIFO function to improve resolution of inclination

I recently bought an ADXL 312 with evaluation boards inertial sensor evaluation board (ISEB). According to its datasheet, the resolution is 2.9 mg/LSB, which would enable resolution of inclination change as small as .25 deg. Furthermore, you claim the built-in FIFO could improve the resolution to as little as .05 deg of inclination by FIFO oversampling technique.

Could you please tell me how should I process in the MEMS Inertial Sensor Evaluation GUI v1.0 ADXL312 Satellite interface? I tried the FIFO function using GUI interface, but it still gave me 2.9mg/LSB resolution...
