What is the test for finding that a party has shown good cause for relief from default and that the party has "articulate a satisfactory excuse for not presenting a defense"?

finding that a party has shown good cause for relief from default and a finding that the party has "articulate[d] a satisfactory excuse for not presenting a defense . . . ." (Rappleyea v. Campbell, supra, 8 Cal.4th at p. 982.) Particularly in the context of the trial court's exercise of its inherent equitable powerrather than, say, the application of a standard set by statutesuch quibbles over phrasing have little persuasive force.
