That's pretty much verbatim what was told to us when the system was announced.
And, you will notice it was also never completed (the near-empty tables at the bottom). Petra's not even a staff member anymore.
Hence, the need for a more complete writeup, especially one that actually reflects experience using the system and collecting the ingredients.
If you want an idea why just going by the original information is bad, look at Tailor BODs. We went 8 years or so thinking they worked like Smith BODs. when it turned out that somewhere in the implementation, at a point never announced - or even documented IN the code, instead of the 50% chance of exceptional of Smith, Tailor BODs were coded with only a 33% chance of exceptional (1 in 3 instead of 1 in 2). Even some DEVS didn't know this until a bunch of us documented drops for 6 months, and saw the 33% - at which point Draconi and others went in, and found that the code said 1 in 3.
Prior to then, everyone went by what was said pre-release, that they would function exactly like Smith BODs (we went through all the archived publish and patch notes that survived, and NONE of them gave the final info).
Of course, someone directly involved with the BODs turned out knowing, but never bothered to tell anyone or answer questions (which is why we would ask the company rep "Why aren't we getting 50% exceptional?" they'd turn around, ask the person who knew the code "the players are reporting not getting the correct number of exceptional Tailor BODs" (WHICH IS NOT THE SAME THING), and the person would reply "We tested it, and there's nothing wrong with the code" (which again, is a correct answer for the CR, but not the question that the players was asking). Only when someone at Origin/EA who THOUGHT they knew the answer asked the person who still knew about the 1/3 coding specifically REFERRING to the 50% everyone thought was the drop rate, that it got figured out - somewhere between 2008-2010, and people had been noticing the discrepancy and asking about it (AND SCREAMING ABOUT IT HERE ON STRATICS) since AT LEAST the launch of Age of Shadows in 2003!!!
