Sorry, 49.7 was my typo when I posted, the chart says 49.5 min = 0.825 deg. My following calculations were correct I think.
After I posted that, I read on page 54 of Russian translation (page 49 of English translation) of the report of Miller's committee that the committee recalculated runway center (ARP) coordinates N54:49.50 E032:01.60 from WGS84 system to SK-42 system and got N54:49.56 E032:01.62, "the linear shift approximately 166 m to the South". However, using the calculator achawk.narod.ru/TransCoord.zip (second tab when executed), I got entirely another result of that recalculation: N54:49.5046 E032:01.7143, the shift 123 meters about to the West, almost exactly same azimuth as the runway. Please check.
