profiling question

[Amanda Clare]

I have a profile that looks like this:

COST CENTRE          MODULE     %time %alloc
 
GC                   GC         164.9    0.0
subsumes             Cover       98.7  945.8
sub                  Cover        0.6   75.7

compose              Cover        0.2    4.5

and the detail:

            fits         Cover       397920    0.0   0.9     99.9  93.0
             subsumes    Cover     -1452515424   98.7 945.8     99.9 
92.1
              sub        Cover     42784164    0.6  69.4      0.6  69.4
              c_unify    Cover      6760353    0.4  15.9      0.6  26.7  


What does 945.8% mean for my "subsumes" function? Are these percents not
out of 100 then? Could it be taking that much time because it's doing an
exceptional amount of memory allocation?
