Why it could happen

Hi All

I received new email notification informing me that my design got a rating of CH, one minutes later the rating was changed to 0. 

Why it could happen.

Thanks for answer

It happens when client change his/her when rating. 

Thanks for explanation although i have not understood the couse

The contest holder has the ability to change ratings at will.

They may change ratings often when they see a new batch of entries.

The entry they loved yesterday, they hate today and visa versa.

Somtimes they realized they rated the wrong entry.

It may go up or it may go down on a whim.

Just think of it as part of the contest holder's "process".

At least he is paying attention to the contest.

Thank for explanation

CH does have the power to assign value to an entry, but at the  time  they are wrong in giving rate it is very sad as happened in my entry

"The Moving Finger writes; and, having writ, 

Moves on: nor all thy Piety nor Wit 
Shall lure it back to cancel half a Line, 
Nor all thy Tears wash out a Word of it."

Good advice

Thanks of all
