Take a look at Bob Hazle. Hazle hit .403 in 1957 over 155 plate appearances. Didn't play in 56 and hit .211 in 1958 over 129 plate appearances. Seems like a guy that the Adjust/Make bad settings would crush. But look at his ratings. Over 52 games so far he is crushing it.
3 year recalc, double weight the current year's stats. Random debut.
