tRA Changed to tERA

As a few of you have noticed, tRA was on hiatus for a couple days. Now it’s back, but as tERA. Quite simply, tRA is on a runs allowed scale and not an earned runs allowed scale, which I believed caused some confusion, especially when I placed it right next to xFIP, which is on an ERA scale.

It seemed the natural thing to do was to compare tRA to ERA/FIP/xFIP and with tRA on a runs allowed scale that didn’t quite work, but now it should.

To convert back to tRA, just divide by .92.
