- Oct 12 3:59 AMAnything beyond 5, or possibly 8, in the faux-Fibonacci series is a WAG dressed up with precision. When given the choice between precision and accuracy, I'll take accuracy, thanks.I've written about this exact issue: http://practicalagility.blogspot.com/2011/06/fibonacci-must-die.htmlOn 2011-10-11, at 11:02 PM, JackM wrote:
As you get larger you need bigger margin for error. You can discern between 1 & 2 less so between a 40 and 41 pointer so that's why fibonnaci works well

Then the next story which is twice the size of that one let's say then you'd give that one a 5. Remember there is no 4 as you should use the modified fibonaci sequence 1,2,3,5,8,13,20,40,100. You can also ad 0, 0.5 if u wish.
