They've done more than the one trial on this.

 From the ACMA trial report that was sent to this list recently 

"The previous trial reported that when filters were connected to the 
test network and actively filtering performance degradation ranged from 
75 per cent to a very high 98 per cent between the best and worst 
performing filter products. In the current trial the corresponding 
performance degradation varied across a greater range—from a very low 
two per cent to 87 per cent between the best and worst performing filter
