Guys, stop picking on the nitty gritty. Brian has produced a great video because there are now a lot more people who
has an idea about what the heck an Accumulator is. Like I said before, if you want everything to be 100% on the spot exactly, Brian would just read the book out, and that, 1)wouldn't a lot of fun, 2) will not inspire further understanding from TGM newbies.
Anyway, having said all that, for those that are arguing about Rolling /Throwout Action, please look at digrams in 2-K#4/5. They
both show the consequence of Throwout Action per paragraph 2 and 3 of 2-K. And what does the caption say in 2-K#5? Answer: "Left Wrist Flat, Level,
Rolling"
