That's pretty much the order I have - so basically what you're saying is that there is not enough restriction in the loop for the serial setup to benefit it and the parallel setup would do the trick and improve the flow significantly?

Also, considering what the current values and scaling in series are any ideas what numbers for the parallel might be?

For example currently:
1 D5 = 130,
1 DDC = 160

2 D5 series = 200
2 DDC series = 200 (I've adjusted from 205 for GPU serial to parallel change)

2 D5 parallel = X?
2 DDC parallel = Y?

I realise it's hard to tell with that many variables but perhaps interpolating from some existing tests I could have some idea?

P.S. Sorry for double post it - didn't notice this post before replying earlier.
Your guess is as good as mine Luke.

I'm busy trying to test out Churchy's point to see just how much of a concern it should be but, I need to go to work now and I won't be able to work on it for at least 8hrs. I'll try and get something done when I get home but can't guarantee anything, may take a couple more days to see any results for this as I've got a couple planned posts full of pics already in the works that I'd like to get rid of first.

While your waiting, could you check the flow meter to make sure it's setup properly? Something sounds really off if there's that much difference from Martin's (or even Andrea's) calculator.
