Their 0-60mph tests are done the way a typical driver would do: mash the throttle from idle RPMs. They don't pick the best time out of a dozen clutch dumps (or brake releases for autos) at thousands of RPMs. They are also more consistent than others because they own their own track, as opposed to some other reviewers who just drive around a press car for a few hours in some foreign country on roads they are unfamiliar with. They also buy their cars from dealers, like everyone else does, so we don't get souped up cars shod with "unfair" tires or brake pads.

Yes, their scoring is kind of useless, but they give you all the data and their driving impressions, so you can judge the car for yourself best on your own metrics.

And as always, it is just one out of many other sources one should research.
At least JD power is a random survey and not bias survey as in CR subscribers only. My guess is that the ratio between the CR sample size for Toyota and BMW is at least a 1000 to 1. Statistically, the much smaller BMW sample size should have been thrown out.
The CR's road test are painful to read, their numbers are all over the place. As an auto enthusiast, I find their road test the least useful among all the major car magazines.
The only segment of the CR I like is the long term reliability testing, but again, the sample size is too small and they really need to combine it with long term reliability surveys outside of their reader's surveys to make the data meaningful.
