Re: Timing is reported to nearest hundredth in ViewNX2 Jim...

Yes, you're correct to point out the possible problem.  I was shooting with the lens cap on and those files are only about 20 MB -- these NEFs must be quite compressible since there's no detail, which makes them not a very useful test subject for this purpose.  When I shoot with the lens cap off (with the books on the bookshelf in my office as the subject), the files are more like 30 MB and the frame rate is definitely slower than 2/sec.  (Even more reason to go for the faster cards...)
