George gave a very good explanantion of why Ammano's CO2 readings 
might vary with his KH/pH/CO2 table readings.  But he did not say 
that you _need_ to be that accurate.<g>

IMO, it is important to use _good_ KH and pH test kits.  Then use 
a table that has good definition.  While this may not give you 
pinpoint accuracy, that is not terribly important.  If all three 
parameters are within reasonable limits, you're all set.
