Nostalrius Begins - Quality wow vanilla realm (1.12)

I've seen people using this macro to /emote their standings and amount of honor to next rank. My question is what is the macro? and how does it work? Don't you need to know where everyone else stands in order to calculate your own?

Any input would be cool. I can't find anything here in forums.

nevermind Ifound it here:

/script P=(math.floor(GetPVPRankProgress(target)*10000))/100 W=UnitPVPRank("player") N=(W-6)*5000+5000*P/100 Q=(W-5)*5000-N*0.8 SendChatMessage("Rank Progress: "..P.."% ".."Current RP: "..N.." RP to next rank "..Q.."","emote")
