I dug back into the archived Strategy Forum (Arm range studies) and found this post by Dean. I have used it in my player evaluations, since reading it several years ago. I just interpolate to get the value for each arm rating (a bit sketchy):

[quote:51b3a11e3b]I think the +5 was on the order of around 5 wins a year relative to a 0. [/quote:51b3a11e3b]I really don't think that's possible. Run some more seasons
I did the LF/RF arms. Since the setup is always the same, I'll shorten the descriptions. It's always 50 repetitions per test, and the original team always scored 650 runs.
Original LF arm: Endy Chavez, -2
Test with -5 arm: -6 runs
Test with +1 arm: +6 runs
Original RF arm: Shawn Green, 0
Test with -3 arm: -2 runs
Test with +3 arm: +5 runs
So to sum up what we've got so far:
C range 1: -13 runs
C range 3 (original): 0
C range 5: +7 runs
LF arm -5: -6 runs
LF arm -2 (original): 0
LF arm +1: 6 runs
CF arm -3 (original): 0
CF arm 0: +2 runs
CF arm +3: +17 runs
RF arm -3: -2 runs
RF arm 0 (original): 0
RF arm +3: +5 runs
Catcher's arm is next.Using this chart and interpolating, I would give a (-2) CF a value of 0.7 and a (+2) CF a value of 12.0. Dean's field charts would rate a 2e4 CF as 3.4 and a 3e4 as 12.3. So, this would say the 3(-2)e4 CF has a value of 13.0 and the 3(+2)E4 a value of 15.4 - a fairly close call.
I really miss the Strategy forum and inputs from guys like Dean.
