Yes, sure. Maybe precision is the better term. The Arduino reads 1024 different analog values as 0,1,2,3,...1024. With the code above you would get 0,4,8,...1020 instead, which means that you effectively get 255 different values across the total physical movement. For me this doesn't matter as my pots anyway do not have this precision.
When reporting to DCS the value is multiplied with 64, so the final values are 0, 256, 512, 768 ... 65280.
