Somebody Explain This To Me

A table of league-total baserunning numbers, via Baseball Prospectus. Note that:

EqGAR = Equivalent Ground Advancement Runs

EqSBR = Equivalent Stolen Base Runs

EqAAR = Equivalent Air Advancement Runs

EqHAR = Equivalent Hit Advancement Runs

EqOAR = Equivalent Other Advancement Runs

EqBRR = Equivalent Base Running Runs (Sum of all components)

Year EQGAR EQSBR EQAAR EQHAR EQOAR EQBRR
1985 0 -155 4 0 0 -150
1986 0 -223 0 0 0 -223
1987 0 -143 0 0 0 -143
1988 0 -208 1 0 0 -207
1989 0 -217 1 0 0 -215
1990 0 -232 0 0 0 -232
1991 0 -293 2 0 0 -291
1992 0 -266 2 0 0 -265
1993 0 -292 0 0 0 -291
1994 0 -182 0 0 0 -181
1995 0 -197 0 0 0 -197
1996 0 -212 0 0 0 -210
1997 0 -340 1 0 0 -338
1998 0 -317 1 0 0 -315
1999 0 -299 0 0 0 -298
2000 0 -296 1 0 0 -296
2001 0 -321 2 0 0 -318
2002 0 -310 0 0 0 -308
2003 0 -172 0 0 0 -170
2004 0 -171 2 0 0 -169
2005 0 -174 1 0 0 -171
2006 0 -141 0 0 0 -139
2007 0 -47 0 0 0 -45
2008 0 -66 1 0 0 -65
2009 0 -88 1 0 0 -85

I imagine this pattern continues as you go beyond 1985. I just got tired of copying and pasting.

Why is it that, over the past 25 seasons, BP has all Major League baserunners as contributing -5362 runs via stolen base attempts? Why does everything else add up to ~zero?
