I Already have, 800/81 = 9 71/81 = 9 + 1/2 + 1/3 + 1/24 + 1/648 is just one of the values stemming from the Grand Gallery in cubits, without need of decimals. If you need decimals for your research by all means use them. I have no use for them in my research. 800/81 provides the seked for the Grand Gallery lengths and other related items. Did you know 80/81 is the Sumerian komma? I found it rather curious how 800/81 can morph into G2 seked and will also define a cubit of 27 digits. Does the ratio of 27:20 mean anything in your world? I don't know what you have, but if it is pi related, please do put it in your book.
