I think he's talking about the fact that the all time highest ranked Harem level is way out of proportion to anything you can obtain in game. The top harem level player is only level 132 with 45 girls, but he has a total harem level of 1,194,122. That number is impossible to obtain with his stats.

But it is true that the all-time stats really mean nothing now. You only get rewarded by your weekly earnings in a specific area.
