When I tried the "pile" method for the first time, I didn't spread mine out so much since I was using a garbage bag on the floor. I tend to be a multi-tasker so while I was waiting for the worms to dive deeper into the pile, I'd be off doing other small chores and come back to scoop off the worm-free stuff. I don't think it took more than 60 or 90 minutes to complete the task, including prepping the bins with fresh bedding and food.
