Numbers over double percent repeats

[Daniel Rosen]

How can I modify the code below so that it produces output more along the lines 
of the attachment (regarding the numbers over the percent repeats)? I want the 
number to express how many measures are being repeated, not how many 
repetitions.

\version "2.18.0"
\relative c'' {
  \repeat percent 3 {
    r8 b\mp cis e a e ais a |
    b,8 d b d d d16( dis d8) cis8 |
  }
}
