I think most Rugby League sites are very hit & miss with attendances. So i can't see any other sports sites having them. I've found it's getting the same for footy. Sporting Life used to have all the weeks football results with attendances but not anymore.

Yes but sometimes not all the attendances

Attendance figures are readily available on these pages. So far this season Hull KR have maintained a healthy 3 million per home match in the championship with them taking 72 million to away games.

Huddersfield have enjoyed an average home attendance of between 3, 19 or 9000 dependant on which board you go on.

Salford take an away following of minus the population of of Birmingham.

You're being a bit conservative with the Hull KR figures there
