I'm not sure  agree with the previous 17 either but this one in
particular I think needs comment

> 18.   The size of base64-encoded data is roughly 4/3 the size of the original data.

The link you gives shows that there are 4/3 as many output characters
as input bytes.
The relative size of the base64 encoded string thus depends on the
relative size of a character and a byte. For example in utf16 encoded
xml, base64 encoded data is 8/3 the size of the original as each of
the characters used in the base64 encoding takes two bytes.
