d5200 pattern noise check from DPR raws

OK, all, I downloaded the ISO 200 RAWs from the D5100 and D5200 to check for pattern noise.  The screen capture below is a 400% blowup of the dark spot on the Baileys bottle formed by the studio gobo.  D5100 on left, D5200 on right. Tones in this patch are at 3-5 units, raised 4 stops.  I frankly see no evidence of pattern noise in the D5200 image. Note that the D5200 in this test was current production (serial no 2500306 according to EXIF data).
