Why do you assume that the 88% has to be "countered?" This retrospective study  looked at 139 male patients of whom 122 resolved their gender issues and 17 went on to identity as transgender.   Zucker's  clinic treated over a thousand young patients during his tenure. If we accept the robustness of the data and variable controls, your query seems to suggest that some portion of the 88% would somehow switch teams with a different approach than Zucker's? That the fraction itself is a product OF his approach? You see the problem with this faulty logic, no? That is an untestable question for obvious ethical  reasons.  Sadly, that doesn't prevent histrionic speculation. But, there is something we DO know. The 17 young males who WERE treated with Zucker's non-affirming approach but still identify as TG (the kind of TG person Wente concedes really must be TG) underwent a treatment antithetical to their true identity. That's not speculation - just a fact.
