The way I see it, if its within normal variation, some people WILL report it as having less oomph...and some won't.
In the chart, we're talking about 440 meters vs 469 meters...BUT, we are ALSO seeing people who tested the Lux on the V@ as being in the mid-50k range, as opposed to the 48k range in this review.
So, normal variation means some are stronger, and some are weaker....and, so far, there is evidence that both stronger and weaker versions are out there.
It was probably that way for V1 as well, but there was nothing to compare it to.
I have not measured mine...but it throws pretty good, and I like it.
