Adding a healthy batch of yeast

Here is the batch of yeast we used for this 10 gallon batch. I started with a Wyeast 1056 smack pack and added 1/4 cup of very light dry malt extract and 2 cups of boiled then cooled water. I let that ferment out for 2 days and then stepped it up using this entire starter and adding 2 cups of DME along with 8 cups of boiled then cooled water. After 3 days I poured off the top liquid and added 6 cups of DME along with another 10 cups of boiled cooled water. I let this sit for 4 days to ferment out nicely.

Now that we have boiled, chilled and aerated our wort we are ready to pitch the yeast into the carboys. I took the 1/2 gallon of starter and let it sit at room temperature (70°F that day) until we were ready to pitch. I carefully poured off enough liquid as to leave me about 1/8 gallon of the starter, leaving all the yeast in the bottom of the jug. I then shook the entire 1/8 gallon up and poured 1/2 of the yeast into each carboy.
