What is the preponderate amount of evidence?

In the present instance there has, in the sense of sheer volume, been a preponderate amount of evidence. Heeding Smith v. Smith (supra) I have looked at the totality of the evidence, the circumstances and the consequences. However I am not able to say that the existence of the vessels as sisterships is more probable than their non-existence as sisterships: this is not an instance where probabilities are about equal, but where the absence of a sistership relationship is the more probable. I turn to examining the pertinent facts in the light of the standard of proof.
