27.1 rather than 27 degrees- why?

So 27.1 degrees is the gold standard for the hill slope. Anyone aware who or why that degree was chosen? what's up with the .1? Why not round it to a simple 27?

I believe that this was a case of having had the track set up and deemed "perfect". The slope measured at 27.1°, and is now official.
I believe you may have the story correct. /images/boards/smilies/thumb.gif
 
It just dawned on me that 3/4 a circle is 270,-microscaled to 27 for PWD?- hmmm, might be onto something here..
 
I was unaware that degrees of angle needed to be scaled for the PWD?

270 degrees would sure make for a steep hill angle though. Straight down!
 
I get what you're saying BR that it differs when scaled..
I'm probably connecting dots that aren't there but it does seem to fit a pattern. 90,180,270,360. So far the only theory is that that is just how it is because that's the way it's always been. There's no rhyme or reason to having 27.1 carved into stone- it could've just as easily ended up at 28 degrees had the person that set up the track had eaten their Wheaties that morning contrasted too had they been functioning with low blood sugar while setting up the track it might've been 26 degrees.
 
The first time I set my track up i got it set to 27.1. I used to always set it there each time I re set the track up. I felt it was very important to have as close to the same conditions as the league track. Now I have a car that I know runs a set time on the track i will be racing on. I can get very close in my estimate to how fast a car will go according to the time of my "test car". When I did set my track up and got all the seams tight I was surprised how close the track wanted to sit at 27.1 before I gauged it.
 
Lol, no, my argument is that the scale does not matter. 1 degree is 1 degree whether it's a doll house or a skyscraper.

The number you should be studying is 152.9.
