It would be better to explain what you don't get, as Battery Guru is pretty straightforward. It takes a reading every 2 mins of your battery and show you the result either with a graph or a text file. Then it's up to you to figure out the result, but there again, nothing complicated
Or so I think.

For what uses up all your battery power, its pretty much the same as with any battery powered device.
Videos are big battery hogs. So is leaving on wfi and bluetooth. If you don't need your wifi on, turn it off and it will save a bit on the battery power. If not using bluetooth, do the same.
The brighter your screen, the more battery power it uses. Turning down the brightness will also save on battery power.
Heavy game apps such as Need for Speed with HD are probably bigger battery hogs than most apps.

It is also a very useful app to confirm your battery charger is working. The magnetic quick charger and charging cradles in particular can be a bit fiddly at times and show a charge icon on the playbook battery icon, but may not actually be charging. I use BatteryGuru every evening as I connect my rapid charger to charge the PlayBook overnight.
As for finding out which apps are using the power, you could try taking a few battery readings, start the app, taking a few battery more readings and then stop the app and take some more readings.

The page F2 refers to was probably this one, which I think I actually haven't linked into the main site yet, silly me: PlayBook: Power Consumption
Thanks everyone for your support here. It's wonderful users like you folks who pushed Battery Guru up to #11 yesterday on the Top Paid list! (That, and RIM splitting the games out to their own list, which helped a whole lot. :-) ) For an app which RIM will never feature (policy apparently precludes promoting battery monitoring apps, as it might suggest the battery life isn't as good as people would like), that's pretty motivating.
TheNamelessMan, as noted above you can't directly find how much power various things use. Battery Guru can report only what the OS itself reports, as our apps are severely constrained in terms of what information they have access to. I've done the best I could with what's available (using undocumented APIs in fact) but to get the sort of info you'd like takes some real elbow grease. I've tried to do some of that in the post I just linked to, but there's certainly room for others to add to that and refine the information.
Basically you have to try to achieve stable conditions for a period of more than a couple of minutes, and watch for (preferably) two updates. They happen only once every two minutes, and there's no way to speed that up either. Make notes, watch the readings, try to keep things stable enough that the data is useful, then change to a new set of conditions and do it all over again. It takes time, I'm afraid, but as you can see it is possible to gradually extract meaningful data in many cases, if you're patient.

Battery Guru does work perfectly well minimized, however, unlike many apps, even if you have the application behaviour setting set to Paused or Default. It doesn't use measurable extra power itself, and minimal memory, and will keep recording even when the device is in Standby, so other than the minor annoyance of having the window open it shouldn't get in your way much.

Is there any standard or typical profiles that one can review to determine if the battery usage in standby (with/without wifi, with/without bluetooth) is normal?
My cousin is having a recent problem with excessive battery drain with his 32 gb PB overnight from fully being charged. He only has it in standby mode with the BT and WiFi turned off .. yet he's he's losing 13% when turning it on in the morning which I think is high. I just wanted to compare what he's seeing with expected drain rates to help root cause the problem he's experiencing and was hoping that Battery Guru could help.

So, i dld Battery Guru last week.
I guess it can run "closed" since i didnt had the app running and still it counted the spent battery and showed it and the power spendings at the graphic...
How do i open those CSV's??

There is a free csv viewer in the app world. Load it and it will give you a list of Battery Guru files you can choose from.There is also a csv editor for a small sum ($ 0.99 ) in the app world. I have struggled with loading the csv file into Excel 2010. Basically you have to convert to notepad and load that in a special way. Since you get a row every rwo minutes if you have three hours worth of data you have ninety rows- a lot to look at. I assume Peter has developed good techniques for plotting and analyzing the data. The plot shown on screen in Battery Guru is very helpful.

What may be uncomplicated to you can still be complicated to others, although I agree that there's a certain amount of intuition needed in understanding Battery Guru. But no one has explained to me why I do not see a graph on my Battery Guru screen. No one has explained to me (Peter?) the significance of Power (sure, Power = Voltage x Watt, so what? and what does 1W or .75W mean to the health of the battery)? I have not exported to CSV. is this why I do not have a graph?
Remember the old army adage: when you assume something you make an *** of u and me (no pun intended, and no hard feelings)

CSV file use in Battery Guru
The PB battery has a nominal capacity of 19.95 watts which in current terms is 5400 milliamp-hrs. Thus if you are averaging a power usage of 3 watts you should get a little over 6 hours use from your battery. Most people will not have any need to refer to the CSV file but battery guru makes it available to those who like to play with numbers and it might prove helpful to the tech proficient in trouble shooting. Nothing mysteriious about CSV files as they are often used in data base applications. The PB has an app CSV viewer which can be use to look at this type of file. I am attaching a screen shot of one of my Battery Guru files using this app. The only really useful piece of information not shown in the Battery Guru application might be the temperature reading. Peter could this be added?
