I never said it had pinpoint accuracy. Even pointed out that decimal place differences don’t mean much. 2 whole point differences, pretty easy to see though. Fangraphs metric for WAR is probably a better one the BBRef because their foundation is metrics. They use metrics in their evaluation that BBRef doesn’t.
All I’m implying with WAR is that it is a snapshot. If you wanted you compare two players you wouldn’t say X has 0.2 more WAR than Y. X is better. You might say, I didn’t expect X to compare as closely to Y. Let me look deeper into why that is.
Then you probably find your answer in the other stats.
OK, so you agree that bWAR is flawed. Progress!
And fWAR is accurate within, what, 0.9, if you can ignore decimals? That maybe isn't all that accurate - what's the WAR for an average regular, 2 or 3? 0.9 is like a 40% error.
Anyway, maybe all of this is just semantics over the meaning of "flawed." To me, it just means "not perfect" or "could be improved." I think WAR is a good stat, just one that could be improved on (and will be, especially as defensive metrics advance).
