Subject: Is it possible for pondering to have a slightly negative impact?

I just implemented pondering in my program, but it seems that this has a
negative effect on average search depth in games. Here is my reasoning:

1) My engine is not very strong, so especially in games against humans, the
percentage of the times when it ponders correctly in "indecisive positions" is
low.
(Aside question: What approximate percentages do programs like crafty have?)

2) So, let's say the ponder was incorrect. Wouldn't the ponder process have
ended up loading a lot of "junk" into the hash table and the history table?

Does this even sound reasonable? Has anyone run into this? Or is this most
probably a bug? Any suggestions/comments are appreciated.

Thank you.

Artem
