Yeah!! Even I too stopped giving attention for KD!I've stopped caring about this several years ago. Nowadays I just write the article without even looking at the KD, I put the keyword in the title of the article, put it once in the 1st paragraph of the article and then continue writing normally. If the keyword appears again in the article, good! If not, I don't care.
That would be a little too much, I guess. 120 repeats of your keyword in a 3000 words long article?3-5%
