Hi Eternal:
I read your guide. Like it a lot, and my post is directly trying offer an alternative view from your guide. I got my BK to level 5 as a TH7 in Silver 1. My BK is now upgrading to level 9 as a TH8, hanging around Gold 3.
See, your guide talks about level 6 troops and TH9. I prefer taking my time with each TH level, and enjoy it to the fullest. I play casually 1-2 hours a day at most, and i am in no need to rush to TH9.
