Not is comparable his test vs my deep test.
I used the STP gear was need exactly for prove the diference DW1 and DW2.
I parsed the 40 mobs fights and was used FFXI calculator for calculate the STP Gear needed.
If you want believe in very superficial test up to you.
I dont will discuss anymore about if we have DW1 or DW2. My test not was maked with 200 - 300 mobs i know, but is a lot more deep than these one with lv 10 mobs, without parse and without compare a true DW1 vs DW2, i used everything was needed in my test.
Is very simple and silly test if we have DW1 and DW2. Open the FFXI caculator go to the delay option, put there your weapons delay, check the STP need for DW1 and DW2, log in in ffxi, get the gear need with your thief and hit something with STP gear thief/x and thief/dnc. You will see notice the diference. (Personally i dont like this kind superficial tests, that is the reason for i wasted about 1 hour of my time parsing and do a deep test)
Another quick note i want add. The guy maked ffxi calculator "Is a god in ffxi maths" In the last version of his program he did not add DW2 for thief, i trust on him because his program is a wonderfull thing for help us know our delay, stp gear, skill caps, and lot of more usefull things
