I hate to say it Jarnin, but your math is wrong. Unless perhaps the dodge modifier was less than 8% when you wrote your post that is. For example, if monks cap their dodge at 230 normally, then an 8% increase would be equal to 1.08 times 230 which would be 248, not 236. Assuming that the skill caps you give are correct, your table should read like this:
CLASS | DODGE CAP | MOD
-----------------------
Bard | 155 | 167
Beastlord | 155 | 167
Cleric | 75 | 81
Druid | 75 | 81
Enchanter | 75 | 81
Magician | 75 | 81
Monk | 230 | 248
Necromancer | 75 | 81
Paladin | 155 | 167
Ranger | 170 | 183
Rogue | 210 | 226
Shadowknight | 155 | 167
Shaman | 75 | 81
Warrior | 175 | 189
Wizard | 75 | 81
Modifiers always round down. If a modifier would give you a skill of 200.999999, then your skill is 200, not 201. Modifiers do not stack with each other. If I have five items that increase dodge skill, only the highest modifier is counted. The rest are wasted.
