Be very careful when you do this, and think about what you are doing.

Here is what happened to me.

I made a "hard" set out of ECM, I kept everything that wasn't solved in
under X seconds, although I don't remember what X was.

Now, of course, what I have just done is created a test suite that my
program will perform worst on if it is run for under X seconds.  I will
score zero on this suite, even a program that chooses randomly between
candidate moves will score more than this.

And if the suite is run for longer than X seconds, other programs will
find some of the answers in less than X seconds, while mine won't find
any in that time.  All of the problems that are easy for me and hard for
others have been deleted, leaving problems that might be easy for
others.

So whatever programs you use to determine "easiness" are going to score
in last place when you run the suite for real.
