The question is definition of considerably

comparing the programs I find 5 programs that played without being updated.

1)Gandalf4.32h(was not updated) 62/100 5.5/8
2)Nimzo2000wb(was not updated) 55.5/100 3.5/8
3)Pharaon2.62(not updated) 54/100 2.5/8
4)Gromit3.8.2(not updated) 47/100 2.5/8
5)Zarkov4.5e(not updated) 49/100 4/8

They did total of 267.5/500 that is 53.5%

Today that do so far 18/40 that is 45%
If they do less than 43.5% then I agree that there was more than a small
improvement in the average level.

Another point to consider is the faster hardware of the premier division.
It is possible that faster hardware make Ruffian's task harder because it make
the opening choice more important relatively to the strength of the programs
because there is less hope that the programs will blunder if they get good
positions out of book.

I remember from peter berger's results that ruffian scored better at longer time
control but he compared only time control that were significantly faster than
WBEC and it is possible that the optimal time control for Ruffian is not
tournament time control but also not fast blitz because fast blitz means that
the program cannot take full advantage of better search to outsearch the
opponent by more plies when slow time control means that the objective
evaluation of the position out of book becomes more important.
