In reponse to your question, it sounds like the altimeter you mention would be ok to use because it is apparently a professionally developed design and has some level of widespread acceptance by various groups. My understanding of this altimeter rule is to prevent someone from taking a free schematic off the internet and building a homemade altimeter. Either it could be built improperly and give faulty readings, or it could have been intentionally built to read higher than actual height.
