I wrote up a little spreadsheet to help log your timeslips.
It will automatically graph your runs and a few other neat tricks.
Take a look. Please provide feedback for enhancements or errors.

I'd love to automate a DA calculation but I can't find much on how to calculate DA. Can anyone point me to some info?

 

I have a little basic spreadsheet that all my friends seem to like, but I don't know how to post so u can compare and use.

I like it man,

I'm gonna try it out this weekend, i'll let you know how it goes!

 

This page has some info on DA, i tried to make a DA calculator once.. but got tired of reading..

http://wahiduddin.net/calc/density_altitude.htm

 

Yeah I found his page awhile ago and pretty much came to the same conclusion.

 

thats the one i use

 

Updated again to include locations and prompts for:

Car weight
Fuel level
Octane

Still working on DA

 

updated yet again this time to:

Conditionally format your best times in green so the best can stand out from the crowd.

Automatically calculate split times between foot markers so you can see where you are loosing or gaining time.

Enjoy!

 

Nice, i used the original one last weekend, it was very useful man. I'll try out this one this weekend and see what i think

 

Nice...I'll give this spreadsheet a try..

 

Made a few updates. Primarily 2

1. there was an error when calculating average and best split times.

2. Added an "overall best and avg" worksheet to track improvements from date to date.

 

Updated yet again.

Fixed an issue when sorting sheets by date.

Added:
Place on the form for your car number
Place on the time slip for win/lose and margin

 

i keeps asking me for a password to enter anything....

 

Are you in "design mode" by default? If there are little squares around the Macro buttons you are in design mode.


Hit "Alt F11" and you'll be good to go.

What version of Excel are you running? I've tested it on 2000 and XP without issues.

 

Knocking the dust off this thread...
I downloaded the attached spreadsheet, but can not get it to allow me to input new time sheet. I am running excel 16, so it may be a compatibility issue..
Has this been updated any further?
Can someone point me in the direction of something similar that will work with 2016 excel?

Thanks in advance!
