bending contacts in k-x

I do not know what to say.

After reading a post that said if we bent contacts in battery compartment SR problem will go away.

That is happen to me.After slightly bending a contacts in a k-x I try to take 50 pictures last night and almost all of them come really good and surprisingly sharper than before. Go figure.
I have a few rejects on 1/5-1/15 sec.what is normal.
Battery level was 1/2 full at that time.It was between 17-22 hours an night.

I have feeling that something is loose inside camera before but bending a contacts I do have a feel that is not loose as before. I was reading a few posts that people complaining something is loose in camera and they have SR problem.
I will try to do some more testing tonight.
Strange.
