Innacurate description for synthesis' achievements

From my point of view, Synthesis' achievements (Main Menu > Achievements > Synthesis) include innacurate descriptions.
Taking "Cutting the Carats: Journeyman" as an example, the description reads as follows:

Craft 1,500 items requiring level 31-40 goldsmithing recipes.

That sentence suggests that 1,500 is the amount of crafted items needed to fulfill the achievement. It would be accurate if we are dealing with "1 synthesis = 1 item" scenario. But that's not the actual case because there are synthesis that yield more than 1 item.
Using previous example, Siltstone Whetstone is a level 31-40 synthesis; 1 Siltstone yields 3 Siltstone Whetstone for a given synthesis, which is to say we are yielding 3 items, not just 1, but the achievement meter raises just 1 point.
Hope you understand, I'm doing my best at English... :o

I guess there should be a change in order to reflect the actual achievement: perform 1,500 synthesis.

Best regards^^

PS. Note that this is applicable for the entire category, not just for said example.

Heard you loud and clear, Umo! (Though kinda late, sorry :p)

As you have very convincingly explained, the synthesis achievement descriptions could do with some tweaking for clarity. And so I went in and did just that. You can check out the changes when patch 1.23 goes live. Thanks for reporting!

I'm kinda late aswell! Anyways, I would like to thank you for your kindness and the update.
The ogre rocks! :)
