I've been using the half-point calculator to determine how my plays are doing vs. the closing line. I'm a little concerned because I've read some threads saying that it hasn't been updated for a while and it was already innacurate on some numbers because of a lack of data. Also, I've read that rule changes can make the data less accurate as well.
So does anyone know how accurate it is? Is it still worth using to determine things like closing line value or line-shopping when lines differ across sites?
Is there something else out there that is better for this?
Thanks.
