Subject to randomization theory, observed behavior tends to indicate thus far that NIM yields on comparable salvage between Class 2 and Class 3 systems is horribly skewed.
Part of the good news in going to Class 3 WH Systems is that the spawn counts are higher. Typically, more wrecks == more salvage == more NIMs. However, whereas clearing 15 Class 2 Perimeter sites yielded over 40 NIMs, I have now cleared 18 Frontier sites in this Class 3 and have only 19 NIMs.
One is tempted to second guess the randomness factor typically referenced on salvage drops...
Anyone have similar experiences?
