As we all know, the standard definition of buffer is the amount uploaded minus the amount downloaded, but what is buffer useful for?
Well, it tells you how much you can download before your reach a 1:1 ratio
But some trackers do not require a 1:1 ratio
and for some people, It is important to maintain a VIP or PU status, and that requires more than 1:1 ratio
Let's take Bitmetv for example, first we need to define some variables
let U = upload
D = download
SB = buffer as we now know it (standard buffer) => (SB=U-D)
MB = maximum buffer (amount you can download before reaching 0.7 ratio and getting a warning)
PUB = power user buffer (amount you can download before reaching 0.95 ratio and losing your power user status)
starting from the following simple equation
and the differnet minimum ratio requirements equations
in simple steps we reach the following two equations to calculate the useful buffers from the standard buffer and upload (you can substitute U-D for SB to calculate the useful buffers from download and upload)
MB = (3/7) x U + SB
PUB = (1/19) x U + SB
of course values differ according to tracker minimum ratio requirements
so when you are trading with someone you don't just ask "what is the buffer?"
you ask "what is the PUB?" which is equivelant of "how much can I download and still be power user?"
or "what is the MB?" which is equivelant of "how much can i download before getting a warning?"
or "what is the VIPB on this account?" which is the equivelant of "how much can i download and still be VIP?" ... etc
Ok ok, I am bored to death, so let the mockery begin
