List of interconnected values for Ford ECU

I know this is dreaming but,

Is there a list or flowchart of interdependent Ford ECU values?

So may thigs affect/override others it would be extremely difficult just by going through HPtune to see what might affect other values.

I'm sorry no, this would be difficult for anyone realistically to produce and even then would be so complicated as to be largely counter productive. The reality is that unless you've made dramatic changes to the mechanical configuration of the engine, you can limit your changes to a few key tables and it's then a case of understanding the implications of these changes and how they work.
