Summary:Eclipsing Binaries (EBs) are known to be the source of most accurate stellar parameters, which are important for testing theories of stellar evolution. With improved quality and quantity of observations using space telescopes like {\it TESS}, there is an urgent need for accuracy in modeling to obtain precise parameters. We use the soon to be released \texttt{PHOEBE 2.3} EB modeling package to test the robustness and accuracy of parameters and their dependency on choice of parameters for optimization.
