How would we know if a theoretical million PowerPacks had been sold and installed though? Unlike the cars, which are consumer products sold to individuals that would feel inclined to post here, PowerPacks are sold to companies. Unlike a car purchase, I can't see a company manager creating a thread to show-off the powerpacks the company had just put in. Given this lack of visibility, how would we ever know that PowerPack installs had happened until they blindside us during an earnings release?
