That's pretty much what I gathered. But I did all the measuring at what should be full power, at least that was as far as I could turn the potentiometer. I measured what the blower was drawing from my 12v (10a) battery charger and got about 9.5v on the output wires going to the blower. Then I measured again with the source connected to the DC controller at full power, there was about a 2 v drop in output = 7.5v. I didn't have an anemometer at the time (just ordered one off amazon) but it definitely sounded like less airflow when the current dropped.
