  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.
