The data would be most easily kept current by being available on the web. Unfortunately, as we have seen, printed matter simply muddies the water after a period of time.
I'm not sure that Jim's and MCA's goals would be aligned. Jim may like to get a return on investment for his time, which is certainly understandable. Whereas MCA would simply make it available at no-cost to members. Personally, I like the latter solution, even though it might not be optimal due to logistics of who would administer the data and presentation.
Whatever the result of this is, it needs to be available on the web.
