I recall discussions here long ago about the difference between slope angle measurements in degrees and percent. Tonight on Jeopardy in the combination of a clue and correct response, they said Talladega race course turns are banked at a maximum of 33 percent. According to NASCAR, the steeper curves are banked at 33 degrees, or about 65 percent.

I remember the original topic. If I remember correctly it had more to do with blowhards than anything else. But this is RSA so.........oh well.

But what is 100%? Is a horizontal line 0 and the vertical of a 90 deg. 100%? "per cent" of what? 360? Never gave it much though. I remember a section of "the peak" at Park City that was supposed to be 54 deg.(?). It seemed straight down.
