Default RE: Just what is "Nitro"?

Nitromethane is usually used with rich air/fuel mixtures. This is partly because nitromethane can provide power even in the absence of atmospheric oxygen, and also because nitromethane tends to produce severe knock and pre-ignition. Rich mixtures cause ignition problems and a lower combustion speed.

And therein lies the reason a rich needle setting is a bit more critical with higher percentage of nitro blends.
