This isn't an endorsement of Race Technology, like I said, it's what I use because it is what the people around me use. It is the only DAQ that I have experience with and I have only been using it for a year.
If you click the image it will take you to SmugMug and you can view the screenshots larger.
Here is the first page I look at. Basic track map and a speed graph on the bottom. The straight lines under the speed graph are time slip. As you scroll through the graph it will show how many seconds in front of or behind the other car is. The red lines are my wife Angela and the slower lines are blue and represent me. On the top side of the map it looks like I (blue) am way off line, that is gps shift, there are ways to correct it but I don't care, the shape of the map is what is important to me. See the 180* at the right of the map, that was a left turn. See how the blue line goes way out? I overcooked the entry, too much steering input, chattered the front tires and blew the exit. About the middle of the speed graph you can see Angela's speed below mine but then she is able to pick up the throttle earlier and was going a full 8 mph faster into the slalom than I was. That's huge. I can go on and on but I gotta get back to work. That's just a small look into how much information is available.....and I don't even know what I'm doing
