While this is true, and something we need to make a decision on, it's also true that using constants in a table or defining them elsewhere and just referring back to them forces the reader to bounce around to retrieve the information they want, interrupting the reading flow. It's a trade-off that needs to be made between ease-of-reading and ease-of-maintenance. I'm not sure we've struck the right balance, but I just wanted to point out that there are some other concerns with this, as well. Easy to maintain docs are useless if they're too hard to read.
