I read this before SR posted, so I fired up my buyers account and made 3 purchases.I cancelled one right away.I marked the next two orders as sent.One I cancelled, selecting 'Never sent' as the reason.The other one I cancelled, selecting 'Never received' as the reason.In NONE of the cases was the buyers stats affected, and in all cases I got the full amount back I had spent. (The price of BTC hadn't changed, and I don't used hedged escrow as a vendor.)According to a query I had with SR before, stats are ONLY affected if it goes to the resolution center, and sometimes it's 'ignored' in the resolution center if the vendor is unresponsive.
