Touch ubuntu-rtm/15.04 language packs translation percentages counted wrong

With the new potemplate stats for ubuntu-rtm/15.04, langpack-o-matic now correctly counts the overall available translations for touch. All is good, but now when considering which translations to include, the count of how many translations are in a langpack seems wrong - probably counting all translations from the merged tarballs instead of only those that matter (for touch). Example snippet from latest l-o-m execute log:

Translated strings per language (2967 translatable in total):
  aa__750 (25%) discarded
  af__4482 (151%)
  am__7320 (246%)
  an__3007 (101%)
  ar__9581 (322%)
  as__10413 (350%)
  ast_15301 (515%)
  az__4317 (145%)
  be__12129 (408%)
  bem_101 (3%) discarded
  ber_0 (0%) discarded
  bg__15997 (539%)
  bn__9820 (330%)
  bo__762 (25%) discarded
  br__6727 (226%)
  bs__34295 (1155%)
  ca__21530 (725%)
  ce__282 (9%) discarded
  ckb_164 (5%) discarded
  crh_7387 (248%)
  cs__23177 (781%)

1155% translation ratio is NOT a valid thing.
