BP comes up with new pitching statistic

I can hear some people saying, "oh, another pitching statistic; that's all we need." However, Baseball Prospectus has come up with a new stat which it claims to be superior to ERA, FIP, and x-FIP, called "Sierra," The formula: SIERA = 6.262 ? 18.055*(SO/PA) + 11.292*(BB/PA) ? 1.721*((GB-FB-PU)/PA) +10.169*((SO/PA)^2) ? 7.069*(((GB-FB-PU)/PA)^2) + 9.561*(SO/PA)*((GB-FB-PU)/PA) ? 4.027*(BB/PA)*((GB-FB-PU)/PA) The description of some of the factors which the formula accounts for (like GB pitchers being hurt less by walks due to the GIDP possibility) is intriguing. BP hasn't shown us how pitchers stack up on this stat...yet. I'm sure we will hear more in the future.
