What percentage of profits genetrated in the hobby are the result of dipping, doctoring, reholdering

I suppose one could include initial holdering, but for the purpose of this post, what percentage of the overall profit generated in the hobby is the result of dipping, doctoring, or reholdering (including upgrades)? If SecurePlus makes grading more consistent based upon an image archive, and doctoring is substantially reduced, is it logical that the short-term impact on the hobby will be less churn, less profit, and fewer dealers? Will the long-term impact be a safer hobby with a greater number of dealers and more collector activity?
