TPS40170EVM-597: OCP Point

Part Number: TPS40170EVM-597

We tried the OC protection on the TPS40170EVM-597 with electrical load. however, we found the real OCP value is NOT matching to what we calculated. Please find the waveform here.

Could you help to check if the calculation is correct or not? Or is this behavior normal? What we need to pay attention? Thanks.
