No brainer or not, it would make sense to have lighting which suited the conditions you expected to use it for rather than compare two lights which fall far short of the purpose.
This for example.. "Power settings were set to full power. Camera settings during the day shots were at 1/1600 sec ranging from f/6.3 to f/8, ISO 50." Why would you use the Einstein at full power when its duration is 1/700s at full power.. thats half the light wasted in every condition you would consider wanting to use the power.
Similarly on the comparison test, 1/8 power.. why?
And the water test at full power and 1/1600s, again, why?
I've seen a few of these reports, or mentions recently with 1/1600s shutter speeds and Einsteins used at reduced power. Surely doing that defeats the object of having the power in the first place.. Does the Einstein work where 1/8 power = 80Ws?
Anybody have a scale of output and flash duration for the Einstein or any other lighting for that matter so that an output/benefit scale can be compared?
There must be a better solution than wasting half your output if using 1/1600s leaf shutters, having to do the maths of what output will work to best benefit where, would do my head in... Something like a Bowens 500 Pro Monolight at 1/2900s duration, or a Quadra and Action Head @ 1/2800s duration comes to mind as being useful , both for full output.
