We couldn’t have a fixed rating. Sure, it may seem like a good idea from our perspective, until you think about the ratings that go from no thank you to love and shortlist. Would you want a fixed rating in that case? Of course you wouldn’t. You only want a fixed rating right now because you’re seeing it from a negative perspective. There are many of us that can attest that it can go the other way as well. I’ve had it happen several times, actually. I’ve even won a contest with a submission that had an otrt, then a nty, then a love, then it went to like and then went to love and shortlist all in the matter of days. I remember this one BECAUSE of all the changes and how it had me on the edge of my seat for the entire contest.
As BrandLander has pointed out, the system of ratings is what it is to help the CHs be able to use ratings as a way to categorize things and make up their minds as the contest goes along and evolves. Thoughts and opinions can evolve over time with the more submissions that come in, ideas that are submitted, ideas from SH (if they have help), ideas from partners, etc. Many things can change the dynamics of the contest and how a CH is feeling about entries. Allowing the ratings to be changed can have drawbacks, sure, but it can have advantages too. The site is not built for ‘what’s best for creatives’ but SH does try to make things as fair as they can. However, you have to keep in mind that these are not just ladeeda contests. There is a point to their existence. We are trying to help individuals and businesses to brand themselves and make something of themselves professionally. This means that they should be able to decide and change their minds as much as is needed so they can hopefully finally find something that will be the best fitting for them and their businesses.
Just keep in mind that while there are sometimes downsides to ratings being changed, there can be positives too. In the end, though, only one person is ultimately going to win. Other ideas may be given bonuses for possible use as well. However, in most cases only one entry out of hundreds or thousands is going to be chosen. Any way that can make this process easier for the CH (the ultimate client), is going to be used. Ratings help to categorize what the CH sees as having potential and helping give creatives ideas on what’s working at that time and what is not. Sure, this can change, but you just have to roll with it and hope for the best!
Also, I want to point out too that just because a rating changes a lot does not mean that there is more than one person behind the contest. That doesn’t mean there isn’t either. But, opinions can change as more and more entries come in and the descriptions that are provided that may help to shape those opinions. And there’s other reasons too. I wouldn’t worry about it, though. Just try to use the ratings and any feedback as a way to keep submitting more ideas.
