Hmmm.
What I am using the CW for is pretty straight forward.
I start with the water temp at zero above ambient, and then I creep it up until the radiator can dump the same amount of watts that the blocks and pump are adding in. The C/W is sourced from BillA's thermal-management-testing article for the HE rads, and I will soon add the Swiftech range.
I'd just calculate it straight out, but my aim is to be able to cater for circular-relationships where the heat of the coolant impacts the heat able to be dumped out. Probably wasted but writing loops in java is easy.

Seems to roughly correlate with reality.

What is better for a quick approximation done by an idiot? Not interested in equations that involve star signs etc. Simple maths for quick approximations.

I know the worms I am in with CW. I am contacting a certain manufacturer now as their block's CW values are an order of magnitude better than the Cascade. Err, don't think so Tim.
