Efficent way to send data?

I see where I am able to define my distances, and my outputs. I assume that the first distance (10) corresponds to the first row of outputs (1, 3, 5). From there, you lose me.

You understood it correctly. The distances constants correspond to the outputs constants. To clarify, I could compile them into a table:

------------------------------------------
|Distance range | Out 1 | Out 2 | Out 3|
|below 20 | 1 | 3 | 5 |
|20 to 30 | 2 | 6 | 8 |
|above 30 | 5 | 8 | 9 |
------------------------------------------

I'm tunneling the measured distance and the array of distances into a for loop. The tunnel for the distance array is an auto-indexing tunnel -- basically instead of outputting the array it outputs the value in the array that corresponds to the current iteration. Within the for loop I'm using a shift register to keep track of an index. If the measured distance is less than the distance at the current index I replace the remembered index with the current index, but if the measured distance is greater than the distance at the current index I keep the remembered index. When the loop completes, the shift register contains the largest index with a distance less than the measured distance. I then extract the output from the outputs array at that index.
