We are very close on these stats.
My numbers for 2009, Parimutuel races only no Qualifiers,
(
includes a few small tracks probably with Demolition Derby ruts 
)
............Break Lines......All lines......Break Percentage
all combined......24691.......436017...........5.7%
all pacers........11281.......327401...........3.4%
all trotters......13410.......108616..........12.3%
all 2yo pacers......660.........9991...........6.6%
all 2yo trotters....877.........4010..........21.9%
Subtracting out 2yos doesn't change the percentages much, too few starters
I didn't break it down on track condition, but sloppy tracks is another factor.
