So they can optimally predict the traffic they "loaded [it] up" w= ith.
Dave, you see why I am skeptical of fake traffic.

=
Not to mention= the fact the LTE traffic is distorted badly by its own sources of bufferbl= oat...

However, getting L= TE implementers to understand that the problem exists in the first place is= worthwhile (so long
as they understand it can occur in either/both parts of the path...
