Just a mistake. The example had been 4x100 which is 16, but I changed it 
to 4x101 for a bit less confusion, which as you say is 17 not 20 which 
is 4x110.

(Although not used much, I have used quaternary here for example:

   4x3032_3233_2323

The digits represent the number of extra days more than 28 in each 
month, from Jan to Dec.)
