I think j_kay was somewhat annoyed because many musicians from other instruments assume that drummers don't read or that drum notation is not real music. So, j_kay got excited and jumped on Eccentric’s case. We see from SabianKnight’s post that drum notation, for the most part, abides by the same rules as any music notation.
Eccentric was saying that he was unfamiliar with drum notation. He was not trying to put drummers down. I think j_kay misunderstood Eccentric’s posts at first.
It’s all good now.
