So that everyone can compare how it looks in RoF.
First image shows Dr.I'es in different ranges(.1 = 100m). Second Dr.I with max possible zoom in game. Third image show SPAD at 210m and fourth show typical engament range.
Now everyone can imagine how "easy" it is to shoot enemies at 300m when planes wobble/slip/bounce in RoF more than any game that I have played before
