Thank you so much for such a detailed breakdown of the book. Fun fact: Le Corbusier participated in Ladovsky's experiments. In 1928, he worked on his only project in the Soviet Union, the Centrosoyuz administrative building. The french architect checked his visual perception with a prostrometer, and it turned out that he did not have enough data to become an architect at VKhUTEMAS.
A very complete book is already there since 1990 (French edition): “Vhutemas : Moscou 1920-1930” / S. Khan-Magomedov. / Paris : Editions du Regard, 1990. (2 volumns) ISBN 2-903370-55-9 .Pity no one has translated it into English
