According to my experience, have had 2 air deck sibs and 3 spare air decks all of them lost top air when measured next day with gauge, that's without having a single pin hole. The tech issue with air decks is they work with high pressure, very low volume and seems to lose PSI very fast along deck rigidity due to atmospheric conditions, much worst if kept shaded for days.
I's the nature of the beast. Need to top it at each outing if wanting near boating perfection. It's a imperfect world, need to live with it.
