Total accuracy = 0.6 x DEX + 0.3 x LUK + Skills/Gear Which in your case would be 0,6 * 30 + 0,3 * 4 = 19,2 which seems correct, not taking into account any potential accuracy you'd have from equips or skills This is from a thief formula, so I'm not entirely sure if it's different for other classes
I just did some file digging and I found the accuracy formula for this version. For brawlers specifically it should be ''DEX * 0.9 + LUK * 0.3''. This is different from Warriors which is 0,8 * dex + LUK * 0.5. In this case my accuracy should be c = 28.2. It's even more wrong than I thought. Note: this might change at second job. I do not know yet. I'd have to find out. Maybe a brawler could share?

Turns out the accuracy calculator properly adjusts itself to 0,9 per dex after reaching 2nd job. This was a mistake on my hand. Thanks to both for the help!
