With the sensitive setups on today's race cars a .5lb is huge on the handling characteristics.

Perhaps you misunderstood my comment. The issue was if nitrogen resulted in a DIFFERENTpressure buildup than ordinary air - or more precisely, a significantly different pressure build up.

I agree that 1/2 psi will make a difference in handling that a highly skilled driver will not only be able to detect, but also exploit.

However, data that I have seen says that the differences in pressure buildup are so small that they are almost undetectable. I'll have to do a little digging, but Walter Waddell of ExxonMobil did a presentation to the California Air Resouces Board that had a temperature vs pressure graph of air filled vs nitrogen filled tires. The lines lay almost 100% on top of one another.

And that is where we disagree. I don't think there is any data that supports the contention that nitrogen has any significant effect on tire durability, rolling resistance, pressure buildup, etc.
