Why then does ED not treat the R-27R DLZ sim the same way? ED's R-27R over performs the R-27R DLZ sim, presumably due to the DLZ sim giving more conservative range numbers than the actual performance; wouldn't the same apply to the ER in tail chase?

Hi, The current R-27ER from ED does not match the known data regarding its tail chase range at low altitude specifically. In the attached tracks, for the 900 and 1100kmh scenarios as outlined in the attached DLZ chart (posted by ED "Ракеты в DCS" thread), it does not match the tail chase ranges, missing when fired a bit inside the manual DLZ ranges. In reality, it should be able to hit with a 150 m/s velocity reserve for the proximity fuze to work (also posted in the "Ракеты в DCS" thread, can be linked if needed). While it is not a game breaking difference, it is significant, and it would be nice if ED would look at this. 9km R-27ER, 1100kmh.trk 10km R-27ER, 900kmh.trk
