If we were present at the trial, would we have found that the trial court erred on the issue of proximate cause?

In indicating our conclusion with regard to the proximate cause question, we have endeavored to consider all items of evidence introduced and all arguments advanced, although not all of such evidence and arguments have been referred to in the foregoing discussion. Had we been present at the trial, we might not have found as the trial court did on the issue of proximate cause. However, we are not left with a definite and firm conviction that the trial court erred in finding as it did on that issue. See Guzman v. Pichirilo, 369 U.S. 698, 702, 82 S.Ct. 1095, 8 L.Ed.2d 205.
