Is this of concern? I'm not noticing any problem with the actual images on screen or in print

I will do a test using Dead Pixel Test software and compare the results with
PDML members. It will probably find even more than 10 hot pixels. :)
Extracts from my post of 10th Feb 2004 titled "*ist D sensor noise survey" follow:
I'm interested in making an informal survey of the noise performance of our
*ist
D cameras. Anyone with access to a PC who has permission to run the little test
app at http://www.starzen.com/imaging/deadpixeltest.htm can participate.
One exposure is all that's required for the test however in order to achieve
consistency we need to make sure that each camera is set up the same. I propose
that the test shot should be made as follows:
10 seconds manual exposure (lens capped) 200ISO Daylight WB NR off Saturation setting (middle) Sharpness setting (left most) Contrast setting (left most) sRGB CS TIFF L file
The tiff file can then be opened and tested under the default settings of the
DeadPixelTest application and the information file saved.
I ran the procedure above and the results were as follows:
[DeadPixelText] Version=1.0 Description= FileType=TIFF NumBadPixels=15 0=Hot,2798,135,69 1=Hot,1954,339,113 2=Hot,1809,585,64 3=Hot,726,610,112 4=Hot,726,611,192 5=Hot,726,612,112 6=Hot,2312,753,121 7=Hot,323,766,94 8=Hot,572,1365,116 9=Hot,1627,1400,64 10=Hot,2163,1958,96 11=Hot,2162,1959,113 12=Hot,2163,1959,145 13=Hot,2164,1959,112 14=Hot,2163,1960,98
For what it's worth mine was very average looking back at the results I gathered (which I promised to collate months ago but haven't as yet).
