I accepted the figures in the letter at face-value.

"For example, an STD call on Homeline Complete, Plus or Advanced is 
currently charged at 10 cents per 30-second block.  This is changing 
to 20 cents per one-minute block".

Note that my figures were for "time-cost", not the full call-cost. 
The 45-cent call connection fee is unchanged.
