That graph has to be made for a specific transmission. The ratios in the transmission play a big role to.
For example, I had a 2006 F150. It had the max tow package and heavy duty payload package with the 5.4L, and 4.10 gears. I got really worried after I bought my 2014 Ram because I realized it had 3.21 gears. Well I did some math and the final drive ratio (transmission gear ratio multiplied by rear end ratio) on the F150 was higher than the Ram.
The F150 was something like 11:1 final drive in first gear and my Ram with the 8 speed is somethin like 15:1 in first gear. Learning that made me feel alot better.
I bet 3.92s are nice, but these 8 speeds really dont need such a low ratio in my opinion. Again, I would love to have 3.92s, but the with the 8 speed you dont really need them. In my opinion.

If I'm not mistaken, that is the same chart that was on jeep forum since 2008. No idea if it applies to the 8 speed trans.
