The layout has changed so I thought I would reply with a modern answer.

You just have to go to her "in comics full report" and scroll all the way to the very bottom. She scores a near-unbelievable all 7's!

Per the Official Marvel Handbook (2005 - Avengers edition), her real stats are as follows. All are well within the "normal" range for an enhanced human, (which incidentally fits in with what we see her doing in her comics).

Intelligence - Human normal
Strength - Superhuman (lift 800 lbs-25 ton range)
Speed - Superhuman (peak range: 700 MPH)
Durability: Enhanced
Energy Projection: None
Fighting Skills: Experienced fighter

Her stats in the more recent Official Marvel Handbook A-Z (2008) have identical stats for her as well as a blurb that describes her as a 'surprisingly fierce and formidable unarmed opponent' but by no means possessed of god-like abilities.

As an example, if her stats were actually "maxed out" this fight would have ended within nano-seconds, assuming he could even perceive her within his limited plane of existence.

At the bottom of her page named "in comics full report" you can see her power stats showing a full set of stats.

Comparing this with Thanos' stats shows that she's even got higher average stats than he does!

Another example of someone with full stats is Eternity:

As mentioned by Valorum in the comments, it is possible this is a joke in part from marvel about a superhero with Squirrel powers being one of the most powerful beings in the galaxy. While this isn't necessarily clear from the entry, it is a possibility given the Official Handbook on the Marvel Universe has differing power levels for the character.

Look at the Power Grid at the top right of the page. All stats are at 7 out of 7.
