You sure about that? Just basing off my adapation values (typically 1-2%), INPA would accept a value 1 or 2 points less than what I input. 1% of 2.5=0.025 ie 2.58 was accepted as 2.56. Was just my theory; you know more about INPA than I do so I guess thats put to rest.
Either way, wouldnt a strong adaptation value indicate a failing injector then? (eg, 15% correction?)
