Comment on Kryptos Foursquare with right to left break after addition by Kryptosfreak

Guys, HUGE breakthrough. K4 doesn’t use math. Sanborn said during his Big Techday 6 talk that he cannot do math and he was taught math at summer school. Sorry KryptosFan. Also, he said a little before that that the Vigenere could only be used for K1 and K2, not anything else.
P.S. His K3 chart is there too. Also, All this is at the Big Techday 6 video and comes in at around 10-11 minutes.
This is huge. This rules out multiple encryption methods. KryptosFan, READ THIS COMMENT.
