A Horrible Spreadsheet of Kryptos Modular Arithmetic

I’m not even interested anymore but for posterity, here is my modular arithmetic of the keywords SANBORN and SCHEIDT into K4 of Kryptos once it has been split into two 7×7 grids.

I did addition and subtraction because we have no way of knowing which is necessary for decryption.

p.s.  Don’t you have a hard time caring about a big blob of calculations like this?  I can’t be the only one…
