Since the developers are said to watch the forum I post a few more errors for their consideration:
Jer 33:5 את פגרי האדם should be tagged as "second obj Gram" cf. Gen 26:15, 21:19, 42:25. At the moment it is tagged as dir obj gram.
Josh 11:20 את ישראל should be tagged as את 2 and not as אות1 cf. Gen 14:2 if one is to make sense of the verse. If it is tagged as את 2 it should no longer be tagged as dir obj. (and indeed it is not a direct object!)
Ezek 20:23 בגוים and Ps 106:27 בגוים tagged as dir obj. should be "Loc Gram" cf. Lev 26:33
I think that the statistical rate of inconsistencies must be much higher than 0.1%. In this search alone I got 4 wrong results out of 62 hits - apx. 6 percent which is statistically significant.
