I appreciate your understanding. I've recognized the issues with the CMRR, and I plan to address them by incorporating 0.1% resistors and a trimpot into the circuit. I had difficulty understanding the correct operation of the circuit initially, but now that I've gained clarity, I'll take into account real-world imperfections and work on resolving them.
It may take some time, but I intend to design a carefully crafted PCB and conduct thorough testing. If the results are satisfactory, I'll return to share the design files, in case you or others are interested in replicating it.
Thank you for your valuable time and assistance!
