Finding GODWAIT and BUSH

After many tests with different keys, i find some interesting things, but mainly, 2 word of the main matrix , the main words found are "GODWAIT" and "BUSH", i think these are the most importants,and belong to the original text,  i find others too, but i think this are just coincidens...

Normally in Vigenere a key word is used to decipher the whole text, based on that, I try to use ELYOI to see what result was thrown when applying it to the complete array, by doing this you get the word "BUSH", first I thought I might To be only a coincidence because it is a rather short word, but then to investigate I realize that it is not, since George HW Bush was the president of the time during the inauguration of Kryptos, in addition, the central CIA Where Kryptos is installed is named Bush (George Bush center for intelligence), so this makes me believe that this is one of the words of the puzzle.

Mr. Sanborn in addition to using English words is using Spanish since to find GODWAIT you can not use the English word TUTANKHAMUN rather you should use TUTANKAMON which is its translation into Spanish, in addition to this you must add 1 letter to the matrix, to That this one moves 1 place to the right, like it was mentioned before, no matter what letter is can be an X for example, if this modification is not done nothing will be obtained. The word does not match exactly as it fits starting at "NKAMONT", is "TUTA" is off. I think that this decrypted word is real and not a coincidence since it is a very long phrase and elaborated to be only product of chance.

Another important fact is that to try to match the ELYOI key with the letters NYPVTT to form BERLIN the matrix must move 2 spaces to the right, which perfectly matches the forgotten characters of K3 "Q?"…

I did the same exercise using this time CBAQK but this time I did not get any very relevant words, like to decipher BERLIN, in this case to match CBAQK with MZFPK to form CLOCK should move the matrix 1 space, that is must be added 1 letter at the beginning, doing this you get some words without much sense.with a friend help, i realize that CBAQK could be really.... SEE BACK..... nad that could mean anything... back of what??...

James Sanborn said in an interview that every part of Kryptos, K1 K2 and K3 helps to solve the last part K4, so there must be some keyword in each segment that, when correctly entered into the K4 matrix, will decrypt another word, For me the most clear of all is K3 which makes direct reference to the discovery of the tomb of the pharaon almost "God" (eye with that ...) Tutankhamun, not the same in other segments in which it is difficult to know which is The word representative of the text itself. For example, in K1 what is the representative word? , Palimpsest, poeme, poetry, iqlusion...? Certainly not something clear.
