Ramp Travel Index - RTI

So i came across this with a buddy from work, i guess "flexing" is just the "street" name yo. Thought it was interesting.

Is there anyone here capable of calculating those fomula's? The only formula i can calculate is lots of letters+numbers and lines = not gonna happen.

First off, you gotta know the RTI ramp angle that you're taking the measurement from. The angles vary and that changes the calculation.

Here's an easier way...

Do some research, some neat info about them. They're neat just to know what your number is. But honestly? That doesn't mean jack shit when it comes to offroading & rockcrawling.
