Thank you for the prompt reply.

Unfortunately, I must STILL be misunderstanding something.

My reading of the documentation suggests that the following data

1066093663:0:1:0:0
1066096371:0:1:0:0
1066097939:0:1:0:0
1066155010:0:1:0:0
1066155844:0:1:0:0
1066160322:0:1:0:0

with "RRA:MAX:0.9999999999:1:9999

1066089300: nan nan nan nan
1066089590: nan nan nan nan
1066089880: nan nan nan nan
[snip all nan's across the board]
1066164990: nan nan nan nan
1066165280: nan nan nan nan
1066165570: nan nan nan nan

Should have some non-nan entries, since I am basically asking to return
the MAX value in a "step" if any single value is defined.

Or am I now misunderstanding how RRD handles sparse (ie long amounts
of time relative to step between datapoints)?
