HR as far as I understand it 20% of the blocks are ASIC, 20% are Scrypt, 60% are GPU (I do not know if these are equally distributed).

That's not the issue. The block find distribution is 20/20/20/20/20. About that there is no doubt.

The question is how does MultiShield adjust each algo's diff and as a function of exactly what? We know that before the most recent hardfork, global network hashrate (that is the combined total of the 5 algos) was key, and that all the algos diffs adjusted in response to changes in aggregate hashrate. The question is how much did that change? To what precise degree are the algos currently independent, and to what degree are they still inter-dependent?

I'm not very good at C++ but I suspect the answer to your question lies here: https://github.com/digibyte/digibyte/blob/master/src/miner.cpp#L155

It's an interesting question but I don't understand what it has to do with distribution energy cost.
If we accept that each algorithm finds 20% of the blocks. If we were to double the mining on any one of them, wouldnt it be reasonable to expect the amount of energy that we used to also double, even though the same amount of blocks would be mined?
