Poor results when farming low level items

Get gear with more perception, that gets you better results at obtaining HQ items, your gathering stat is just the chance of obtaining the item while gathering.

At level 35 (I think) you get an ability to raise chance of HQ by 30%.

correct, I'm well aware of how perception works. My frustration stems from Logging at level 50 for flax with perception 313, I notice no increase in the speed at which I gain HQ items from when I was a lower level gathering them. The only difference is the two abilities I can now use that either increase yeild (500gp), which takes a huge amount of time to build back up, or Leaf Turn II (300gp) and so random I hate using it. I thought it was a good idea to level a gathering job first to make it easier to gain HQ items before leveling a DoH, I'm really not seeing this.
