While looking at the newest car in my fleet during this snowstorm (14"!) I noticed the wind was sweeping across the parking lot, over the hood almost directly head on.
The rear glass/trunk area is a near perfect Kamm of snow. Instantly, I thought of grabbing my tape measure and camera for some math to ponder later.
TL;DR?
Get lots of snow. Shape as desired. Measure perfectly. Build once.
