The most recent figures I have from the Credit Suisse case study are 1500 services enterprise wide with a reuse rate of about 70%.
The reuse rate was lower when they started out - which is probably obvious enough - and 70% has been constant for a few years apparently, so we could based on this extrapolate a view of the potential max being around that. But of course the investment in reuse pays off over time.
