You will get the latest, only v3 is available now.

I think I'm thrown off course by your use of "100%" in your explanation.
Here is the real world concern. When I datalog in my car, many times I will see knock retard when RPM (and hence IDC) is low but engine load (and hence MPS) is high. If I triggered entirely from IDC, I would not have WM spraying in this condition where knock is present.
I like the idea of triggering from IDC, but there are conditions where I need MPS to trigger some spray when IDC may be below 12%. It *sounds* like the 70/30 setting is what I want... but I'm not sure!

I would wait until the system is installed and in operation. There are a few other options. Instead of using MAP sensor, you can input the throttle angle sensor. This will give you instant dose of water/meth based on user demand.
PS the system can inject based on 100%-IDC, 100%-MPS or 70/30.

PPS vendors now state their systems operate as high as 250 psi, some vendors reference 300 psi. I assume this is done to provide better atomization. Most of these systems use the Aquatec-5800 pump... can this pump be configured to run reliably at such pressures?

Power at WOT make zero difference between the kits if you live your life in the quartermile tracks. For DD applications, the difference is huge,
I do get feedback from PWM-V converted users. Mainly the system more linear and does not bog the engine on low rpm and does not run-on during gear change. This confirms the theory is sound. More readings below:

Those claimed pressures are what the pump is capable of when dead headed. You would only have found that out after the purchase; The by-pass valve is actually set to between around 200-220 dead-headed. What else is there for a PPS system to shout about?
You can increase the pressure on the on the aquamist pump to beyond 250 psi by adjusting the set screw on the front of the pump if you wish. The pump will heat up quite quickly.
Two water tanks of the same capacity, one 30 feet tall and the other 18 feet. Open up the same drain tap on both, the water level of the 30 feet tank will drop faster.
