Yes, I've seen the labs. No, I don't use it. I don't return batches for re-indexing.
For FS personnel:
Philippines, Camarines Sur, Caceres—Registros Parroquiales, 1716–1977 [Parte B] [MMZN-6DJ]
Batch has two images with 4 death records each. Indexer put 6 in each and marked everything unreadable except for a bogus page number.
