The Load Factors are indeed the average of the monthly inbound/outbound Load factors.
Anyone can access the BITRE figures and check them.
For two months of each of those years, JQ had a higher LF than QF. QF has maintained an average LF advantage of JQ, on figures for the entire two years of 6.1%.
In the Jan 2010 figures it was almost a 13% difference. It would be interesting to see the difference in yield, but I suspect that is Commercial-in-Confidence.
