        I agree, in fact, any time I have an A/D conversion I always try to do
this, and not just with the PIC's A/D. I've found this to be a good idea
even when using external A/Ds and chips that do A/D inside them (i.e.
digital temperature sensors). No matter how "clean" you make things there is
always the possibility of some external temporary influence from affecting
your readings slightly, this method brings some protection against this.
