RC circuit Simulation results do not match look up table

Hello,

I am using this RC circuit simulation with my lab data. I have a 2.35Ah capacity battery, with a discharge pulse of 2.35A (1C). I put my HPPC test in RC circuit as in the picture of LUT code (first column)

In order to match the default RC circuit with my case, I remove all step blocks my setting them 0. Pulse generator is set with Ampitude = -2.35, Period= 3600s, Pulse width 10%, which mean I have 10 pulses, each pulse pull 10% of capacity.

The thing is the paramters that I put in the LUT is different from the data simulated. I put in R0=0.0607 Ohm. After I have the simulation, when get the ohmic voltage drop (the second when pulse start) / 2.35A. I got 0.0640 Ohm. It is close but not exactly. I don't know if I did something wrong or it is how simulation works or we have to do the exact procedure as in default simulation of matlab.

This is the default model: https://www.mathworks.com/help/simscape/ug/lithium-battery-cell-one-rc-branch-equivalent-circuit.html#d126e36758

Please help! Thank you so much in advance
