There are more explanations why your cake was not in the top 15 and had more views and comments.
1. The cakes in the top 15 had more favorites
2. The cakes in the top 15 had more comments of other bakers – the weight of comment from other bakers is little bit greater than the comment of the author.
3. The Daily top 15 is refreshed once per hour. It means that at the time your cake could have more comments, favorites and views than the others in the top 15 already, but changes will take effect after hour.
BTW. could you please send a link to your cake? I see no cake with lots of views/comments from you…
