Hi Frank,
Thank you for elaborating further, I appreciate it.
With regards to your question, since R2 and R5 resistors are the same value of 4.99kohms, the voltage at Vout will be 1/2 of Vref. (referencing your drawing)
Although there is a parallel resistor implementation, You can try utilizing a shunt resistance value of 4.99kohms for Rterm. Per the highlighted portion above, since the voltage can be above or below Vref.
Regarding Current Sense, I will add a capture on the sense ratio to help further.
Kind Regards,
Nouman
