Thanks for your perspective! I’m certainly not an expert in Qt development and appreciate your perspective. This could perhaps be due to our use of the median number of changes as the threshold for rate of change. I’ll make the full dataset available when I return to my lab shortly, so we can explore together to find the most appropriate thresholds for Qt. >> I’m happy to provide a more detailed Qt dataset when I >> return to my lab next week. > > It would be nice to see some reason ("numbers") why files ended > up on the list. I’ll definitely include that data :-) Kind regards, -Shane _______________________________________________ Development mailing list [email protected] http://lists.qt-project.org/mailman/listinfo/development
