Food For Thought

From time to time you've seen data logger tracks published, and here's another.
It's my own track from the Grace Flight race, and it's a mess.
I provide it for entertainment and also for educational purposes.

The data logger I use is built by GlobalSat, model DG-100.  Those of use who play with these things have found it to be one of the better units on the market - other brands seem to loose satellite lock in the turns.  The DG-100 has proven to be rock solid by several of us who use them.

If you decide to use a logger as a tool for evaluating your races and determining what you need to work on, I highly recommend it.  Accept no substitutes!

This logger is widely available at $70.  Here are some links that are valid as of today:

This track of leg 1, from the start to turn point 1, shows both a lack of planning and poor execution.  Knowing I had a turn immediately on the start, and knowing the airplane doesn't turn on a dime, perhaps I should have shaded the way point South a bit.
Compounding the mistake, I chased the course line, overshot, and then snaked my way to turn 1.

In all of these tracks I've added a straight line from point to point - the shortest distance around the course.

The Leg 2 track shows more of the same, but since the distance was shorter, I had less time to get off track.

The track of Leg 3 is a little more controlled.  Actually not bad.  For me.

But Leg 4 was way bad!

This is a look at Leg 4 from the finish line perspective.
I know how I'll fix this in the future (yes, John) but I leave it as an excercise for the student (you) to come up a solution on your own.
