Note 1: Qualified = 1 IP/Game, Current = 33
Note 2: PAP data is only available for current season, but includes all regular season/competition/playoff starts
Note 3: PAP = Pitcher Abuse Points, using PAP^3 formula. This article at Baseball Prospectus is the primary reference. Why is this data relevant? Markus said it is.

TOT_NP = Total number of pitches
AVG_NP = Average number of pitches per start
PAP = Total Pitcher Abuse Points
MAX_PAP = Highest PAP for one start
CAT_1 = 0-100 pitches
CAT_2 = 101-109 pitches
CAT_3 = 110-121 pitches
CAT_4 = 122-132 pitches
CAT_5 = 133+ pitches
STRESS = PAP / TOT_NP
