That's a good read, I wish there was a detailed as database for the A-League.
When coming up with the idea to research this, I had a debate with someone on how often you should expect a goal from a corner, ended up saying in between 1 in every 25 and 1 in every 50 which broadly does fit in with the data.
With the Nix however, not only are they below that (2 goals in 196 corners for a tad over 1%), it was the lack of headers that really surprised, 67 games without a headed goal from a corner astonished me.
They even scored from the world's worst idea - the short corner - more recently than a direct headed corner, thought that was strange.
