Hello i am trying to find a Avoidance Macro for protection paladin 

I have found 3 macros all 3 work but give me different results can someone please tell me which macro is the correct one? 

here is first macro this macro was made for patch 3.1.0

/run dr=function(x)return 1/(1/16+0.9560/x)end;DEFAULT_CHAT_FRAME:AddMessage("Need 102.4 - Currently at: "..string.format("%.2f", GetDodgeChance()+GetBlockChance()+GetParryChance()+5+dr(floor(GetCombatRatingBonus(CR_DEFENSE_SKILL))*0.04)))

Here is second macro this macro was made for patch 2.5.1 tbc classic

/script DEFAULT_CHAT_FRAME:AddMessage("Need 102.4 combined avoidance. Currently at:",0.8,0.8,1)
/script DEFAULT_CHAT_FRAME:AddMessage(GetDodgeChance()+GetBlockChance()+GetParryChance()+5+(GetCombatRating(CR_DEFENSE_SKILL)*150/355 + 20)*0.04,1,0.5,0)
