In the official journal of ICCA 1997 this is the search times presented for

pos     1 cpu  2 cpu    4 cpu   8 cpu  16 cpu

2	2849	1424	791	438	274

Now if i let excel calculate the speedup numbers based upon this and i let excel
calculate the speedups based upon the search times

You will realize that these speedup numbers are frauded. Rounded off errors they
are not, that's for sure.
