Comment (by slink):

 The current implementation needs another review. Looks like we need to
 sanitize some numbers not to get odd results like this:

 {{{
    Hitrate ratio:          10       14       14
    Hitrate avg:        0.9793   0.9794   0.9794
 Efficiency ratio:          10       14       14
 Efficiency avg:      -252.4640 -250.5249 -250.5249
 }}}
