As I read it, the article assumes that the 20% performance penalty measured when writing large blocks is almost entirely due to APFS performance. This seems reasonable, since the number of syscalls will be low.
However, it is then also assumed that this 20% performance penalty between HFS+ and APFS is going to be flat no matter which block size is used. I don't think this is a reasonable assumption.
