I don't know whether that's possible. They calculated the piracy rate by looking at sales versus overall activations. That means they can't tell whether a particular copy is pirated or not, so they can't break out app usage stats into pirate/non-pirate demographics. Possibly they could approximate this by pushing a version update through the app stores, which most pirates presumably wouldn't receive, and then comparing stats for different version numbers.
