Yes, I am sure. I checked the graduation of the radian scale on lighthouses as well. Previously, I carefully determined the height (70m) and the location of the lighthouses using RAOBF before posting the tutorial video (SH5 School of Navigation. Level 1). I also tested my centiradian table on 5 types of ships: only in one case, probably due to an incorrect mast height in the recognition manual, there were erroneous readings. In all other cases, the readings are consistent with each other and with the RAOBF results. Here's an example with a lighthouse. U-boat is located in Narvik at a distance of 1000 meters from the lighthouse.
