As long as your dont select your own model numbers, its 30days or less. I did 4 Form1's in the last 5 months, I was 26, 27,29 and 29 days. If you select your own model, 90-120days is the norm.
I'm curious about this also. I'm about to submit a form1, but thought you had to pick your own model number since you are the builder.
