Hi yamakawa4000
The reason those numbers are low is the protection built into the WinMXGroup patch. It blocks flooders so you will notice that number stays low, the fact is yes there are lots of secondary connectors out there and lots of primary ones too. The Mod3.0 patch your using blocks the RIAA fake file flooding companies that attack the network, they connect via secondary as well.
Its nothing to be worried about as long as your getting good search results and chat list, and your uploads are working the patch is doing as its supposed to.
