I assume you are talking this paragraph;

The 5KΩ resistors are not very accurate. It is interesting to note that IC fabrication doesn't generally allow precision resistors, but the resistors compared to each other are extremely close in value, which is critical to the circuits operation.
Valid.

I plan on resubmitting that article, somehow an old version was used incorrectly (my fault). I'll update my master copy.
