If anyone's interested I've written a program that combines the Pearson's square and a sausage casing calculator. You'll find it here:

You can save batch details with notes and hopefully it'll prove useful to all you fellow sausagemakers out there. I highlighted a bug in Spuddy's square program back in July but I got no reply, I then noticed that Spuddy hadn't been posting here for quite some time and so I decided to write my own.
Hopefully there are no bugs but if you find any just let me know and I'll try to fix them as soon as I can.
There's very little validation on the various field so if you type in something stupid it might crash or give an error! There's no help file either but hopefully it won't be too difficult to work out how to use it.
I hope it proves useful.
Happy sausagemaking
