Over the past two days I've had 6 out of 6 photos accepted and my acceptance ratio went up by 4%. That's OK, nothing wrong there as you don't know what my acceptance ratio is. But today I've had just one rejected and my ratio has fallen by 2%. I'm not saying there's something going on here - it's probably just the way it works - but that really doesn't sound right. Anyone else experience this? Do I take it as being normal?
