Thank you for your reply. I don't have the "Фатьянов А.И. Практическое руководство по выверке и определению поправок штурманских приборов на судах (1976)" and I never heard about it but title sounds interesting. The flow chart which I attached in my original massage is basically the summary from many other Russian books on celestial navigation ("Morekhodnaya Astronomia"). The most well known is Мореходная Астрономия - Б.И. Красавцев - 1978 ( https://deckofficer.ru/titul/
I think the method of complements till 30' of xx' and yy' yields quicker and easier result for I.C.
It might be confusing but: I.C. (Index Correction) = - I.E. (Index Error)
