Your itinerary appears to be allowed by the
rules in that there is nothing prohibiting flying the same segment in the same direction more than once (in other words there is no rule against your multiple SFO-LAX and LAX-SFO segments)
However there is a restriction on the number of transfers at a point
9B. Not more than three transfers at any one city permitted
So your itinerary appears to have maxed out your visits to LAX and SFO.
As you no doubt know - you have used only 8 of the max 16 segments, and the distance of your itinerary is 20,682 according to gcm - so you still have potential to improve it.
I presume that even short hops, in A, are good TP earners (I don't know anything about the BAEC) - in which case this itinerary might be a good earner - 3 times round the SFO-LAS-LAX triangle and close to the 22K maximum of a xCIR22:
HKG-SFO-las-LAX-SFO-las-LAX-SFO-las-LAX-SYD-HKG
(Note: AA starts flying SFO-LAS direct in late August; it's a 1-stop flight - via LAX
)
