I see(hear) it all the time in new pianos that I tune. I often pound my way through the treble chromatically all the way up to C-88, BEFORE I actually start a pitch raise. When I finally start with the tuning hammer, the pitch is more representative of the actual tension of the string throughout it's speaking and non-speaking lengths.
