Whoa, Dave, that's a little harsh, isn't it?  Sure, the tables won't
give you values accurate to 10 decimal places, but they certainly are
useful to someone interested in knowing if they have approximately the
right amount of CO2.  

If nothing else, it makes us anal retentive types happy to know that
the test kits are consistent with each other <g>.
