However, at higher distortion levels the discrepancy becomes large. For instance, a signal with THD F 266% has a THD R of 94%. [4] A pure square wave with infinite harmonics has THD F of 48.3% [1] [14] [15] and THD R of 43.5%. [16] [17] Some use the term "distortion factor" as a synonym for THD R, [18] while others use it as a synonym for THD F ...
THD+N includes everything other than the fundamental, which means intermodulation products, interference, etc. THD without N would only measure harmonics. If you think it is confusing, please try to reword it.

In addition, even-order harmonics are said to be generally harder to hear than odd order.
