We present a status update on the CMU group PWA efforts in the strangeness (K{sup +}{Lambda}/K{sup +}{Sigma}{sup 0}) sector. The bulk of the currently available data comes from recently published CLAS g11a results, with extensive polarization data expected soon from the CLAS g8 and g9 set of experiments. We give a brief description of issues pertaining to different sign conventions for the polarization observables in the literature, and normalization discrepancies between the CLAS-g11a results and older high energy data from SLAC/CEA/DESY that used an untagged photon beam.
