I'm not sure how most programs use there first second of time but
am guessing that some might do stuff that may restrict the full one
second
of calculation. For the new programs wanting easy positions they could
just keep the 770 positions from ECM98.770(or some name like that).

I do now think that 10 seconds is too long. I ran Rebel 8 on
the first 100 positions of ECm98.770 for 5 seconds per position(K6-233).
It found 88 out of 100. If something like 5 seconds were used it would
also
be easier to adjust for different hardware speed. Alphas =4, pent266-300
and Amd =5 and so on down the line (just guessing at these ratios but
the
KKup2 has good data on machine speed ratios). Of course many other
programs
will find more or less than 88 and these will also be different so out
of every 100 maybe 30% will remain, resulting in a suite called
ECM98.230
(or however many problems remain after deletions of the easy). It may
be easier for testers to report the ones they don't solve in X seconds
as that list will be smaller than the solved ones. Anyone not solved
automatically stays in the next draft.

Now that ECM98 is out there people can do what they will with it but
I do believe that the programmers will come to some consensus to further
reduce this suite to meet the requirements they originally set out to
achieve.
Namely, bug free and no easy "WAC-like" problems.
