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
> The trial that the ACMA have done, which I believe they didn't use
