It's only one cent away from a 1/4 tone in EQUAL temperament, but if you are hearing it as the next diatonic interval above a major third in the harmonic series, it's a whopping 15 cents closer to a whole tone than a half tone above the major 3rd. I definitely hear it as F# (actually, on the Bb harmonic series on a trombone in first position, it is quite a bit closer to E than Eb even in equal temperament. I can lip it quite a bit, so it is hard to measure exactly. Perhaps its actual tuning has something to do with brass instrument construction that would not show up on a tube in a lab experiment.) There was some research done in the last 20 years or so on pitch recognition, and there IS a grey area around the quarter tone where people can hear either the note above or below, depending on personal history and context of how the note is played. I'm not saying YOU don't hear it the way you do, I'm just saying there is flexibility when you get far away from the usual 12-tone system that can account for variances in identification, even between two experienced musicians. So I retract what I said about "interpreted by our ears." It's only interpreted that way by MY ears, and I think I could be swayed differently in context different from a scale.
