CV training is very informative and would be considered a must IMO if you are not familiar with the product. One of the gaps that 99% of all vendor based training does not fill (CV training included) is the space between integration and optimization which I often refer to as the transformation phase.
Environmental specific knowledge and expertise is required to fully leverage the product set based on your unique requirements. After attending formal training in OP for CV I would speculate that on your own this phase takes around 4 - 6 months. There are providers that offer Accelerator Services on-site that are intended to teach advanced management and optimization techniques, in essence a transfer of intellectual property as it relates to the technology and the environment.
As I have been on all sides of the IT circle: Help Desk Support, Administrator, NOC Support, Data Center architecture/integration, Consultant, my personal opinion is that the window between understanding and mastering the technology is where most training programs miss the point. The lab training just never quite measured up or translates back to the home base. It is excellent for core concepts such as the CTE, Storage Policies, iData's, Scheduling, etc. but never really cuts down to the best practices level and to take it a step further best practices as they relate to your environment.
Apologies for the ramble gents. Just my .02
