I find enormous benefit from going directly to source documents (10k's, etc.), even though it's slower.
More importantly,
If you just keep going to original source, you will find the brain will be trained for reading thing consistently and knows where to find.
Switching over too many resources and trusting third-party resources for key matrices is big mistake.
