Does anyone know if there is a system tester out there for NRL ?

I am thinking of collecting the data (which I have a source) and put together a simple tester similar to the simple horse racing tester I have. Just wanted to know if I am wasting my time if there is already a free one out there that I could use instead.

If you don't know of one do you guys want me to put what I create on a site for you to also use ?

Thanks
