Most are at least 87 digits at the moment (except for two dozen or so that are in the 7786 digit range). I still have about 80K lines that are not yet in the DB

when someone next works on the faulty ones they will spot the error also once we have inputted them all we might be able to get syd to run his check all sequences thing or maybe when we work on those sequences again

I might take out and submit all sequences above 90 digits, but this requires significant manual work so I definitely won't do this daily.
