Haha...imo you're absolutely right. That is exactly why they ask. But we aren't allowed to ask a CH to rate entries, to my knowledge that is against the rules and will get you in trouble so that's just a clever way around it. If they say go ahead and delete then you know it's not a case where they intend to come back and rate. It essentially serves as a NTY rating.
It really is a drag when entries are left unrated. We are left wondering if they just took a quick glance and will come back or if they intend to never consider it again.
In regards to keeping good percentiles and being a successful creative SH recommends entering a few names and then waiting for feedback before entering again. But when you get no feedback do you move on or continue to shotgun ideas, potentially affecting your ranking (which definately affects your ability to freely participate) in hopes that you're on the right track??
I kinda wish ratings were mandatory. It's not like once rated it's set in stone. We all do this knowing we aren't gauranteed any money but it'd be nice if we were atleast guaranteed ratings!!
It is a bit extreme tho, huh? Lol
