PMP23126: Why is there such a large deviation in the calculations used in the schematic and in the program?

Part Number:PMP23126

I don't think it matches up in the schematic and in the program, is there some other documentation for that?

#define PSFB_VLVBUS_MAX_SENSE_VOLTS    (float32_t) 16.13

My calculation.

3.3/(1.82/(1.82+37.4+0.1)) = 71.29  

#define PSFB_I_LVMAX_SENSE_AMPS       (float32_t) 500

My calculation.

Rshunt = 0.001/10

Vout = Rshunt * 100 = 0.01

Vlv_fb = 0.01 * (7.5 / (7.5 + 2.49)) = 0.00750

Imax_sense = 3.3/0.00750 = 439.56

Please tell me why my calculations are so far off from what's in the program.

thanks
