I really don't relish the idea of having to debunk other researchers work and do not consider myself the final authority of Ancient Egyptian mathematics. But will offer this assessment of your proposed pi figure. It would seem you keep pushing this idea with limited understanding Ancient Egyptian mathematics. The fact is and remains if they were unable to express these terms or values how could they possibly be used in calculations or designs?
2.2222222222...= 2 2/9 fractionally, in Egyptians fraction series = 2 + 1/6 + 1/18
99/70 = 1 29/70 fractionally = in Egyptians fraction series = 1 + 1/5 + 1/7 + 1/14
140/99 = 1 41/99 fractionally = in Egyptian fraction series = 1 + 1/3 + 1/33 + 1/36 + 1/44
One small point just so you will know it is not a seked of 14/11. G1 is properly known as a 5 1/2 seked and has a rise of 7 to a run of 5 1/2. Or if you prefer to eliminate the fractional component is noted as a rise of 14 to a run of 11,
The fact is my calculator goes a just few digits beyond what excel is capable of and as previously stated: Given the square root of (800/81) or 9.8765432098765...= 3.1426968052735445528926416093548846190437152786154401626148438622016277299157934196675278540614257171889196582909162156109 440801241127493614313811046665240698071614798389013172351110011136728490234921557990221591243783878546596933660633720414241 982191323385094010762415873810018661391191733227809066437494519923251817973992013791450185608778994350006394665816218568338 229722930155807874991186855529936897486666015533440334012089506451476761062734855398598191590679521402479925971400289235968 199716383006411316996916655504787151853787301524578104054935047635233053679237932617008267169967660035241781379463277605904 946671301298814492129775319876379836870667358640547707015739178001321908231118192178538210882840645868989050304180697199678 346927382311655758283778282091394608060623323862464372231151933040818779390665254953468362215425289945899608286660400726227 720934731709166353449291121021871445758044998758537174514395790674674157949575961931810467046914853147959393087599463814627 004729398929974382421543630806425695295035450300312316150340532654705580648005352701133633667678625083466783625484482505339 231043267200667816656264139834736411529252173336820820393070783063742338417416954198254001457487930413254655901114766054466 304213415305162476420923503668979742031760751362680116519176634037888701715013841221647642220417826138735478236809359616259 391683421321593902076971641405025517205827130380346310222058935947228219816757751465219200185460189292160515142675712058909 014516296440969906368437325598371760888611925816035516841911696363595172213320487563950563736502706086220432336438291720148 662955533100859397384125285994999250044370185612835997642939656321634877322139893708647745538975343901841854502436720214539 754210085881390544283458626587578482177406804115598620855422349236297156773485645724151110378047493865…
I found your proposed pi figure to be quite irrational with no indicator of a fractional value. So please do let me know if you find a repeating sequence in the above? I will leave it to you to work out the Egyptians fractions for your proposed pi figure.
Sorry David, but I only did that to demonstrate the component part of your proposed Ancient Egyptian pi figure as it relates to Ancient Egypt. Sadly, the fact is, regardless of what you think you see in this figure, it seems to have no relationship to Ancient Egyptian mathematics!
Given the fact no one has proved the Ancient Egyptians preformed calculations using anything other than unit fractions, seked, cubits and binary additive multiplication and division as demonstrated by the Eye of Horace series. Until someone proves otherwise I will stick to those known factors.
