I guarantee that, with some effort, you could write a script to emulate every HTTP call -- logging in, accepting the cookie (just a value in a Set-Cookie header), and requesting the point values, making sure that cookie value is in your Cookie header. Just because you could "only get it to work" one way, does not mean there isn't a far more efficient way.
