Two other advantages (correct me if I'm mistaken) of self-invented PINs
are, I think,
1) One can prepare and remember the PIN in advance, so there is practically
no need to write it down;
2) A PIN letter is only something I have, while my own PIN record is in
addition something I know. i.e., it may not be obvious to someone else to
be a PIN record / reminder.
