I think that it is dependent on the programmer and you cannot generalize.

There are programmers who do almost no progress in software and there are
programmers who get significant progress.

programs that did significant progress in the last year are mainly weaker than
the commercial programs(Thinker,Fruit,Gothmog) but it is possible that at least
one of them may become better than the commercial programs in the near future.

I am also not sure about progress of Shredder and Junior since the last version
and we will know better when the ssdf tests Shredder9 and Junior9.
