How many hours do you get off a charge?

Apple claims that you get 9 hours on a new rmbp, one charge surfing the web with safari on 75% brightness (12 clicks).
How much do you really get?

I get 7 hours on my mid 2012 cMBP browsing the 'net and writing.

I force the integrated graphics card using gfxcardstatus, my brightness is at about 25% and I use Chromium build 235555.

Previously, on Mountain Lion, I would get about 4.5/5.5 hours.

Thats very good but how about 75% brightness?

For some reason, I typically get 9 hours of light browsing with brininess fluctuating from 60-100% (Mid 2012 cMBP.)

Late 2013 rMBP doing light/medium load work for school (Aperture photo organizing, Web, Pages, Numbers, Etc) I get about 9 hours with keyboard backlight at 1 click brightness and screen at about 45% (7 clicks backlight).

Allow the brightness to get higher for editing, photoshop and music.
Usually try to keep it plugged in whenever I'm in my studio space, class or home for a solid amount of time.

I opened this thread because i noticed that i only get 5 1/2 hours of netflix on full brightness.
Also the battery app predicts 5 1/2 hours atm with 90% charge and only light browsing on 12 clicks (75%).
Apple claims 9 hours. doesn't this seem kinda low?

What you are getting is pretty good.

Apple's numbers are for light web browsing not watching Netflix which obviously uses a lot more CPU power.

Apple don't measure with Netflix running, it would be like Ford quoting gas mileage at 100mph...it just isn't going to be pretty.

so i guess this is for the rMBP 13" because for the late 15" is 8H apple claims. So i get around 8h 45min for web browsing at 50% brightness
