Potoatoe Cooking Amount? I'm currently lost as to how much i should cook them

Here's a breakdown of the recipe. The potatoes cook three times (steps 3, 6, and 8). The first time, they boil. The second time, they fry at a low temperature. The third time, they fry at a higher temperature.
1. Slice potatoes into 1/2 inch thick sticks
2. Soak potato sticks in cold water for 30 minutes
3. Boil potato sticks in salted water for 8-10 minutes, or until tender (start the potatoes in cold water and bring to boil)
4. Drain the potatoes and shake them in the pan to rough up the edges
5. Freeze potatoes for 30 minutes
6. Fry potatoes in small batches at 270 degrees for 4-6 minutes, until starting to color. Drain on towels.
7. Freeze potatoes again for 30 minutes
8. Fry in small batches at 350 degrees for 2-3 minutes, until crisp and golden
9. Salt and serve
