That is just the N-reg trustee. He has about 200 planes on his name.
The usual procedure is to google on the tail number.
It's all very sad and so pointless. I am used to flying with a fuel flowmeter accurate to 1% and I can usually tell if some airport pump has been "adjusted" to over-read by a few % (this is sometimes found in the more southern parts of Europe). It's easy to forget that the vast majority of GA pilots, even twins, fly without accurate fuel instruments and therefore on guesswork. Conservative guesswork usually, and OK if one remains very conservative. Unfortunately, if one is sufficiently conservative to be safe, one ends up chucking away a large part of one's usable range.
