I do not know patio11 but I am pretty certain he does more than present and run, and so can charge more. I get the impression from his blog that it is more a case of the client committing to a certain project (ie 250k worth of developer time, plus his fees, in order to increase metric x). He leads the project, enthuses the developers, puts the charts on the wall and basically earns his keep.
Three months later they have enough of his brain cells in their heads they can wave goodbye.
Personally I would love to sit in an armchair at the Diogenes club and have people come pay me for my opinion on what they should do. If that was ever a consultants role I think it is long dead.
Yours
