Agreed. Its been my goal to try to either find or create such a test. So far
the WM-test is the closest I've seen to predictability. Assuming all answers
are correct I think a test set should have at least 1000 epds. The more the
merrier to avoid randomness. Just like games the small sample size could sqew
the results and lead to answer chasing. So far I'm leaning towards 50%
positional, 35% tactical and 15% endgame. Test set should contain a mix of easy,
medium and hard. I'm unsure as to the time. I'm thinking maybe 5-6 minute for
the positional and 1-2 minutes for the rest.
