If you think about it, if you hit an already stunned monster with DU, both hits will have the critical opportunity, and at the same time continue the stun. Meanwhile, if you use FF, you only get 1 hit in and it's only a 60% multiplier. My belief is that it follows the same concept as Arrow Blow and Double Shot.
That's exactly how I use it. I use backspin blow>Double Upper. It gives twice the chance of a critical, without having to do BackSpin Blow>FlashFish>BackspinBlow>FlashFist. The combo I tend to use on single targets is BackSpinBlow>DoubleUpper>FlashFist>Repeat. It seems to maximize the amount of criticals you can get with the two, and gives Backspin Blow's cooldown a chance to wear off before using it again.
Other than that - I didn't really use it in second job. There were more places to train where you can mob and use sommersault kick, than Double Upper. So, personally, double upper didn't get really amazing until after Critical Mastery was maxed.
