Well, I'm glad someone undertands what I'm doing and that I wasn't really proposing anything REALLY different.
You're right, I guess for someone trying to gather info it can be confusing to see another method (or view of the same method) introdced, so I'll just step aside and live with the process the way I choose to use it.
The anodizing by PAR , I thought, was being proposed by Caswell, along with their LCD method since it is included at the end of their manual. The LCD process works well and they have definately simplified the process using it. It does have it's limitations. But I'm not so sure introducing the process of PAR is a good thing. I've not been able to prove that it works - at least for small batches like I do. (Apparently someone has shown that it is dependant on the size of the batch (current), making it even more difficult).
The 720 calculator is a good tool to have around. It's also a good thing to understand what your doing rather than rely on tools blindly. It makes it easier to figure out why something isn't working when you know how it works.
I'll go back in my cage now.
Thanks guys
