To be honest I am not quite sure. It could be anything from penciling stuff in and they caught it, not totalling up their times right (I spent 10 hours of the course of 2 days making sure every column was correct in my log book.) I had slashing and line and marks ups all over the place but they seemed to be okay with. Or I could imagine that they posted they had this many house of total multi etc... on my airlineapps.com and I guess when they handed over their log books they double checked and saw they lied on airlineapps. Just don't lie about anything with them and you should be good.

Actually sorry one other thing that might have done it. They want each checkride in your logbook flagged and tabbed so they don't have to go looking for it page by page. Maybe some of others didn't do that. But i flagged the page and the put a sticky arrow pointing checkride date in my book.

Hope this helps.
