right. I don't say that my explanation is the Truth. But I'll assume that's it's "true enough" until I hear another plausible explanation. Both explanations -- or all five etc. -- might be "true enough."
(one explanation that complements the other is that WalMart sales are an okay measure of US economic activity in general these days.) At least for me, "true enough" has means "true enough to act on" in some way. In the case of this hypothesis, the "fact" is so trivial that it doesn't really matter.
