Some Results:
After having used it in 2,523 public works projects in 2007 and over 4,000 public works projects in 2008, the Japanese government has recommended that critical chain project management “be used on all projects henceforth (approximately 20,000 projects per year).”

APM Body of Knowledge. "An alternative to creating networks based on activity dependencies is to use a technique called critical chain. This method considers the availability of resources and the interdependencies between resources.“ - APM Body of Knowledge 6th edition (2012) p 155
Association for Project Management
PMI Body of Knowledge “Critical chain is a schedule network analysis technique that modifies the project schedule to account for limited resources. Initially, the project schedule network diagram is built using duration estimates with required dependencies and defined constraints as inputs. The critical path is then calculated. After the critical path is identified, resource availability is entered and the resource-limited schedule result is determined. The resulting schedule often has an altered critical path.” PMI BoK 4th edition. Ch 6 Time Management p.155

‘Critical Chain Project Management presents us with an opportunity to plan projects well for maybe the very first time. We should make sure that we break with our old traditions of how we have done things in the past, and re-plan our projects from scratch.
But planning is only half the story. The real power of CCPM comes from the control afforded during the execution or deployment of the job. Buffer status and buffer management allows us unprecedented feedback on the progress of the project and where to focus attention and where not.
And maybe this is the most important factor in the whole approach.
We have a totally new and systemic way to manage projects. We should make the very most of this opportunity.’ Dr. Kelvin Youngman
