Multiboxing not working?

So I have been multiboxing for about a month now and it has all been pretty good, except I only used 4 Characters. I recently noticed that most people have at least 6, and so I tried to use more accounts as well; however, when I tried to do it, it said that 4 was recommended. I have an iCore 7, so I dont feel like 4 should be the recommended. Am I doing something wrong? Skype: jackson.rekt

Kronk bases the recommended on the numbers of cores your CPU has. It recommends me 2 but I can easily run 6, it just goes by the number of cores=number of characters rule. The real question here is why tf youre only running 4 with a bloody i7, you could run like 12 if you had good enough internet lmao
