Did you miss all the strong:G0,G0 entries?
Your file StrongG0
described as with all "the missing Strong numbers" contains 7111 unique entries that match the non-greedy regexp "strong:G0 lex:\S+"
(but without the double quotation marks).
The file lxx.osis.xml
also contains 2112 unique entries that match the non-greedy regexp "strong:G0,G0 lex:\S+,\S+"
(again without the double quotation marks).
Had you taken account of these?
