Well that's the trick isn't it, your math actually says that you'll see a ~3% difference in pressure for a given amount of air.
If that given amount of atmospheric air is at 30 psi at X temp then nitrogen would be approximately 3% less pressure so that's a ~1 psi difference, you've totally validated my estimates!
Math is fun,
