I'm not familiar with the intricacies of the STA standard, will have to check the parsing and the contents of f2 when I have access to a computer.

It's IVTFF.
"<->" are illustrations that separate words, they should be processed like ".", not ignored if you want to extract words.
"{...}" for example "{cko}" are unusual connected glyphs (other than the most usual 'benched' combinations starting with c/s and ending with h): they should not be removed.

eyeballing the ivtff, the discrepancy you observe is due to chokeos<->chees being processed as asingle word by the parser. it shouldnt be much of a problem (since cho count also decreases, not just che count, what's more this combo is not that common) but i will upgrade the parser and rerun the tests just in case there are unforeseen side effects, i appreciate your help !, thansk
