I am struggling to fully grasp the differences and characteristics of Accumulator #2 and Accum #3.
Spending alot of time with the Yellow Book but perhaps it's something right in front of my eyes that I'm confusing for some reason. Accum #1 and #4 are clear to me I think.
Any advice to help me understand, direction to a good thread here or supplementary descriptions from any member's experience would be greatly appreciated.
