You misunderstood it :) Actually I found that pretty clear, let's take your examples :

Example 1

But lets say D+T is 100. There are 2 bugs.

100/100=1   so for every 1 bug do -0.008

that is 1 - 0.008 * 2

Example 2

D+T=1000, there are 2 bugs.

1000/100=10.   for every 10 bugs do -0.008

-0.008 * 2/10 = -0.0016

bug ratio= 1-0.0016 =0.9984

I think you understood "for every" as "times", which is well... the exact multiplicative inverse :)

EDIT : as Istrebitel said, it's not truncated
