I checked your guide. All makes sense. But I cannot use KGR.
For my keyword, there are reddit & twitter links in top 10.
Top 10 positions have not been fixed and there has been lot of movement there.
All in title says 152,000 results so KGR value comes out to be 152,000 / 1000000 = 0.152 [ I know its only for KS less than 300 ].
All seems positive as of now. Will keep tracking this keyword.
