Hello again Evgeny
I found the reference in the Cert guide and started reading, and I realized that the two formulas are actually the same. This is because, for multiplication, the order of operations doesn’t matter. For example, if you have
256 * (a+b+c) * d
this is exactly the same as
256 * [(a+b+c) * d]
which is also exactly the same as
(256a + 256b + 256c) * d
You can replace
- a with (K1Scaled Bandwidth)
- b with (K2Scaled Bandwidth)/(256 – Load)
- c with (K3Scaled Delay)
- d with (K5/(Reliability + K4))
and you have the same thing. So it seems that both formulas will indeed bring the same result, because they are actually the same. I think the number of brackets has made it more difficult to see.
I hope this has been helpful!
