Error on Argus' performance page

[Nicolas Braud-Santoni]

Hello,

I just wanted to point a little mistake on
http://qosient.com/argus/performance.htm :
It is pointed that, by using two 80/20 optical taps, one after
another, one would experience a 40% power loss on the link, and get 2
outputs @20%.
It's obviously wrong, the result being :
    100%                              80%
========> TAP 1 ==============> TAP 2 ======> 64%
                      |-----> 20%                           |-------> 16%

Good afternoon
