I don’t understand your point. Reviewers preferred the old model in 17.6% of instances and did not feel it was an improvement in 37.7% of cases. Together that means in more than 50% of cases reviewers felt the old model was as good as, or better than, the new model. The new model is undoubtedly better than the old model but given how bad the old model is I don’t think these results are encouraging.
