In the comments to my previous post Mauricio asks:
“I am excited about the Final Version. However, I have to ask, how is the Final Version superior / more conducive to productivity than Superfocus?”
The main difference is that both SuperFocus and AutoFocus tend to result initially in the minor/easy tasks being processed first, while the “squeeze” is only put on the more difficult tasks gradually. In the Final Version this is not the case.
An associated problem with SuperFocus/AutoFocus is that there is a tendency for the list to get packed with easy tasks which give an illusion of progress. What is actually happening though is that the easy tasks on a page get dealt with quickly, while the more difficult tasks only get dealt with a few at a time. So typically a new page will have 30-40 per cent of its tasks dealt with on the first couple of passes, but in later passes the proportion of tasks will fall dramatically. This results in a large number of active pages.
In the Final Version there is no pay-off for packing the list with easy tasks, so the length of the list is dramatically reduced. The processing of tasks is much more even throughout the list, with the result that the list tends to be concentrated on a few pages (my current list has 4 pages, but there are only 2 tasks each on the first and last pages).
Also unlike SuperFocus/AutoFocus, the Final Version list is dealt with as one list. The page divisions are not significant (and in electronic versions are not needed at all).
