I have been using Blendzall 501 for years for the same reason, and it smells better. We don't go as rich as you mixing only 1 pint per 55 gallons, I think you said you mix a quart per 55 gallons.
Your ratio is 240 to 1 or .00417% if you substituted nitro at that percent I still don't see performance enhancing qualities in your fuel.. I don't think they make a hydrometer accurate enough to catch it and probably under a spectrometer analysis it would come up under trace amounts of hydrocarbons.
The guy saying you was illegal has probably never done a fuel analysis IN a previous post.
However on a "good nose day" I could probably catch you.
