  CP violation in the lepton mass matrix will be probed with good precision in
upcoming experiments. The amount of CP violation present in oscillations can be
quantified in numerous ways and is typically parameterized by the complex phase
$\delta_{\rm PDG}$ in the standard PDG definition of the lepton mixing matrix.
There are additional parameterizations of the lepton mixing matrix as well.
Through various examples, we explore how, given the current data, different
parameterizations can lead to different conclusions when working with
parameterization dependent variables, such as $\delta$. We demonstrate how the
smallness of $|U_{e3}|$ governs the scale of these results. We then demonstrate
how $\delta$ can be misleading and argue that the Jarlskog is the cleanest
means of presenting the amount of CP violation in the lepton sector. We also
confirm that, among the different parameterizations considered, the standard
PDG parameterization has a number of convenient features.
