What format is the track?
I encounter this all the time with mp3's, not with lossless audio.
It could be intersample peaks.
It aint. I have the track too. Imported it, warped it (with a tempo change), it peaked as he says. Turned off warping, peaking at solid -0.2.
...also I kind of doubt that on-track meters would include ineterpolation into a measurement.
