# Thread: Mathematical review of buffer theory

1. As we all know, the standard definition of buffer is the amount uploaded minus the amount downloaded, but what is buffer useful for?
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

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

2. please some1 translate to english

yeah, that's the point

Anyways, I didn't bother to read the whole post.

SB > buffer as we now know it (standard buffer) => SB=U-D

Half of it doesn't even make sense..

5. 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

6. Strangely it all made sense to me ...

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

7. prima1 - i think u didnt take the right pills this morning...

8. damn, i took the night one this morning

9. 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
