Re: your web page for road grade

Tom,

nice web page for road grade calculation.  if you key in 5000 feet and 1 mile, it sould calculate
something a little less than 45% grade, instead it give 294.71% I believe you have a glitch in the
calculation someplace.   Try a rise of 5280 and a run of 1, and you get something really big.

Thanks.
Dave

My response:

Hi Dave,

Thanks for trying out my site!  Do you mind telling me what search engine led
you to it?  Are you a cyclist, too?

I tried to be clear about how grade is calculated, but maybe that part needs
more work.   The distance you enter is the distance along the sloping road, not
the horizontal distance.  The horizontal distance is hard to get - that's why I
made the calculator work the way it does.  You don't enter the horizontal
distance at all.  Instead, you enter the distance directly off your odometer.

If you wanted an angle close to 45 degrees, you could enter an elevation of 5000
feet, but the distance along the sloping road would be close to 7000 feet, or
about 1.34 miles.  If you key in 5000 and 1 mile, you have an angle of about 71
degrees, not 45.

I hope this explanation was helpful.  If not, please write again!

Tom

You're a very accomplished person!

Demand valve? I just finished my SCUBA rescue course which of course included O2 use in emergency
situations with both demand valve and continuous flow units. I took FORTRAN WATT IV or something
like that in the early 70's. About that time the Commodore 64 came out and I bought a 300baud modem
for it. Rather than sit through the punch cards, I dialed in from home and got my homework done.
Soon enough there was a line at my house. I never went further in programming and I regret it now.

In the 80's and 90's I did a lot of programming in Clipper for dBase applications. It was all hobby
for auto racing clubs. Now I dive a lot, and ride road bike. No running for me. I recreate the club
rides for people with Garmin units so they can "ride" the course, get prompts, know elevations ahead
of time, etc. It keeps me real busy.

I live in Newport Beach. Someday we'll meet.

Regards,

Fernando Maldonado

Hi

I visit your web-site and I am really impressed. I wish that I could do the same
but I can't. I came to your site from Sportstracks I saw you question about fuzzy
map; I have just upgraded and discovered exactly the same.

Thanks and have a nice day

Best regards Carsten

Hi Tom,

I was visiting with Jenice and she told me about your website, so thought I would visit it.
I'm so happy to be able to see pictures of you running, cycling, entertaining, etc.  Also
enjoyed the family tree.  That's quite a bit of research.
