Shouldn't A Tactics Trainer Problem's Rating Be Determined By Its Pass Rate?

     I see quite a few Tactics Trainer problems with a 1200 or so rating and then
a pass rating of about 20%(even after about 2000 attempts).
     Isn't the Pass Rate the only real factor that should decide a problem's
rating or are there other overriding considerations?

People have commented about this a lot.  I also don't understand the low rating problems having a tiny pass rate.   It would be great if they could link the rating to the pass rate...must be possible but requires some reprogramming?

zankfrappa, could you please send me the # of such a problem the next time you encounter one, and i'll look into it.

There is partial credit in the tactics trainer. If a player gerts the first several moves right and the last move wrong it counts as failed so it lowers the pass rate. But the solver gets partial credit for the moves that were correct and the problem rating can go down.

In short, the pass rate is not the only real factor that decides a problem's rating.

indeed.

dpruess,

Yes, I will send some problems to you as I spot them.  I recently sent one to
Patzer24 as well.

I have also spotted some typo's in the Chess Mentor courses.
