"More often than not" would imply that the majority of sticker autos appear in products upside down, which is false. For that matter...besides your card, I haven't seen any other upside down stickers this year, and none since a couple Cam Neely cards in seasons past. That's hardly "More often than not."
Look, having worked quality control in the past, your sample sizes can't be 100% for products as large as Upper Deck Series 1 and Series 2. Every time you call into a CS organization and are told "Your call may be monitored for quality purposes," it doesn't mean your call's going to be used in the QA environment. Is it a fair assumption that just because 100 (a random number) Signature Sensations autos ended up on QA's plate and all of them were placed on correctly that all 7500 of them are right side up? No...but you sometimes have to put your products forth based on what you've been provided and have case studies of.
