OK, no problem. When I was sober for a few years, candidly the 12 X 12 did not make as much sense as it has in the last 5-7 yrs.
As you probably know, it was published in the mid 50's many years after the BB was, so a great deal was learned.
I have heard of the BB referred to as the owners manual & the 12 x 12 as the service manual. I like that.
Both serve a great purpose.....and seriously not looking for debate. Was only attempting to share my personal experience re taking steps quickly.
Best to you!!!
