Speaking personally, I would want any stress test to be the MOST stressful possible across all laptops for the baseline. Turn off cache (how often do you have the console open), run a VM, sit on a Hangout, all at the same time. Make the fans whirr hard.
If you want an "econo" benchmark go right ahead but I don't know why one would criticize Consumer Reports for being hard on a laptop browser. (It obviously makes sense for hardware makers to dispute the technique as it's harder to hit "X Hours" markers that are tested)
