Legacy had enough of an impact to keep Marvel ahead of DC in $.
And while there were Legacy arcs launched in November, there were no new #1's, no new series and no events.
Contrast that to DC, which had a lot of major firepower but still had to settle for splitting wins in the Diamond categories with Marvel.
Look at it this way - if during the height of Secret Empire, if Marvel had filled the majority of the Top Ten but still couldn't beat DC in dollars, that would signal a bit of a problem in regards to their overall line.
