You are basically correct. Our latest results are summarized in
vsnet-alert 6221 and 6223 (and see oc.gif). However, our O-C analysis
has shown that Masi's double do not precisely fall on the expected
superhump timings. We need to assume a slight variation of the superhump
period, if these peaks represent growing superhumps. Identifications
given in vsnet-alert 6221 are more secure.
