I think the refund thing your talking is somewhat correct. I have had 4 INRs and they don't seem to be leaving defects when I have been refunding. Although I think I got defected for doing one and also resent something one time and that didn't count. Seems like ebays system is not working properly.

I think they also stuffed up the cancel transaction part of ebay as well, as it basically does different things all the time.

Also with that message from ebay about it not counting towards seller standing, when a refund is made, I was thinking that might be for just the refunding part, as in you won't get a defect for refunding. It would be nice if they just said how it worked, although they could get into trouble if they are forcing sellers to refund to prevent a defect.
