Rebeckah,
I've emailed re: hist data a few times and did get a positive response resulting in a needed correction. It seems they input draws manually rather than by downloading from official web sites ... GH will not search for errors but will correct specific ones, so as Beak pointed out the diff in my stats I'll have to find the exact errors, then tell them ...
Andrew,
they let me know they are busy, busy ppl so I don't think they have much time to discuss other softwares 
Cheers
Sorry for my delay in responding, I couldn't get online....
I would imagine they enter winning nos by hand cuz downloading & then converting from an official site would take longer for them? They have @ 100? games in their database to update weekly by hand, {what a boring job) So, yea, errors will happen. Brad, I think it's great that you emailed them the corrections! That kind of selfless behavior will make you a luckier lotto player.
I have emailed them once & never heard anything & then a month later figured it out myself.
