Yep - that's just my experience is that pXRF results are all about the sample presentation to the small window that the instrument reads and detects in, the more homogenized the sample (whether by percussion drilling or by intentional sample preparation such as pulverizing), the more accurate and precise the portable XRF is likely to be. I'd bet that when you go back and check your particular experience you will find that the wildly inaccurate/over-optimistic or imprecise pXRF readings would be from raw/unprepared diamond drill core samples and not aircore/RC chips.
