The range has to include your own, but truth be told If you make an open seek with your rating as the max and 500 points bellow your chances of getting a low rated player are quite high.
rating range

Thank you zxb995511 you are right. I forgot to mention that I wanted to specify and practice an opening which I don't usually play and I wanted to guarantee a lower opponent because of that. I would still like the system to allow "downward seeks" such that my rating did not have to be included in the rating range.
I would like to be able to create a seek with a range of ratings below my own and not including my own. As it is now, all seeks must include one's own rating in the range. I understand that makes sense so that people don't seek "up" too much but why not allow people to seek down if they feel like it once in a while. This would be beneficial to lower rated players who could accept such seeks.
