    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

    SB=U-D

    and the differnet minimum ratio requirements equations

    for MB
    U/D=7/10

    for PUB
    U/D=95/100

    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

    I know, lol, i am not a native english speaker and i didn't study math in english, so God help you understand this

    I made some changing maybe it will make more sense

    Strangely it all made sense to me ...

    But I think keeping to the definition of buffer = GBs above 1:1 makes things more simple.

    I for one applaud your efforts In practice, SB is really completely irrelevant, as a 1:1 ratio has only cosmetic value most of the time, and the important figures are, as you say, MB and PUB. There is definitely a case for encouraging the use of these figures in trades. Now how about formulating a relationship between buffers and invite value to standardize what a certain buffer is worth on a tracker at a certain level? That's your next challenge
