You want to use this formula

Upload speed / ( # of clients * 8 ) = sv_maxrate

I will go with your lower upload speed of 139K or 139,000
To be honest you need to experiment with the number of clients. some people say you can host 4-5 some say 6- 8
we will calculate for 5 and 7. Once you see what your connection can handle you can redo the equation

Let's recap

upload speed 139,000
number of clients 5 and 7

so far our formula looks like this
[code:7ad6a]139,000/(5 *8)= sv_maxrate
13900/40= sv_maxrate
3,475 =sv_maxrate for 5 clients[/code:7ad6a]
or
[code:7ad6a]139,000/(7*8)=sv_maxrate
139.000/(56)=sv_maxrate
2,482 = sv_maxrate for 7 clients[/code:7ad6a]

Remember to always perform the calculations with in your parenthesis first

If you need more help or want to calculate a maxrate for an different number of clients let me know.
the big thing is finding the right combination for your upload speed.

good luck
