one step at the time mate.when luffy saw mihawk cutting his arms that was observation haki.a glimpse.aisa had huge observation haki.he knew what was happenning  round her.who was dying,where enel was,who beat who,etc etc.thats huge observation  haki.rayleigh said the haki exists in all people.in 2 form.observe and attak.the third form intimitation exists only in some people.through training people can use both of them but they tend 2 be stronger in one of them,due 2 many things.mostly their character.check the issue that rayleigh xplains it 2 luffy.that means that someones attack haki due 2 his character can  be like a wrecking ball,he can beat a logia  with little effort his observation haki wont be his strongest.he can see attacks and feel people but not like aisa and cobby. cobbys observation haki is better than luffys.he has more potential at that.rayleigh said that with observation haki u know where people are and what will do in the next momment.u can litterally fell them.cobby felt tme.if luffys haki with mihawk is rated 1 then  cobbys haki at marineford is at least 50.and unlike enels priest he didnt even have 2 focus.small observation haki huuuuge observation haki. u ask me how he knew what the marine were doing??? simple mate.half of them where pumped up and wher chasing pirates and the rest of them where gutted by a sword and bleeding.what a man that bleeds heavy feels?? pain.and he felt that.the pain that was coming 2 them.through his observation haki. cobby aint luffy.dont compare luffys observation haki with cobbys observation haki.or aisas.both of them could hear and observe in miles,lyffy only something important,like a heavy injury. like comparing luffys fighting strenth with cobbys is a joke, luffy 50 rank cobby 1 rank,the exact opposite happens when u compare their observation haki. if observation haki can be ugradded,trained in such a level that allows u 2  read poneglyps that i dont know and is a good theory,but keep in mind that with observation haki u can see and feel the living things,their aura not the non living.
