It's obtuse/specious/spurious to take someone's simplified, illustrative example, that everyone else understood to be exactly that. . . and rail against it for post after post while claiming that it was used in ways it never was (as a "fact", etc.).
Here are more numbers for you to bizarrely attack. . .
Imagine a server with with a capacity of 1000. After 1000 clients connect, it begins to bog down.
Now, that server can handle 1000 individual players/people/souls using it at a time.
Or, it can handle 83 people running twelve clients each.
Your ridiculous harping on "50%" is the same as you reading that and then harping on "83 people" for the next page or two. It's the epitome of intellectual dishonesty.
