5.16 and 5.03 and 5.01 are different
I found that 5.16 found some moves faster then 5.01(I did not download 5.03 from
chessbase)

Mark young found that 5.16 is sometimes faster and sometimes slower than 5.03

I remember that 5.03 had better results against chessmaster in 1 hour per game
match of Mark young against chessmaster6000 and CM6555
I think that the results were Fritz5.03:CM6000:5-1
Fritz5.03:CM6555 3-3
Fritz5.16:CM6000 3-3
Fritz5.16:CM6555 2.5:3.5
But I am not sure about it and I may be wrong.
