Hi Linus,
Yep, this works, the last 4 bytes of each 23 Byte pattern are binary
floating point numbers that actually correspond to the detailed profile
data that DM5 shows.
The old pattern was blocks of 16 bytes (without the 7 Byte header
block), where the depth data was in bytes 3 to 6.
Now I need to find a way to find out which format the SampleBlob uses
(new or old) as no indication is in the DB data, but that shouldn't be a
problem.
I'll implement the new data import at divelogs.de tomorrow, @Miika: this
might be something for you too :-)
Nice one, thanks Linus :-)

Could be though, that they adapted the format to the EON Steel data.

Looks more like a fixed-size (23 byte) repeating pattern. The
sampleblob seems to be this:
- 7 bytes of header (probably some version information):
03 00 00 00 00 00 00
- followed by this pattern of constant-sized 17+6 byte blocks (the
last one lacks the 6-byte thing)

but I never looked at the old db4 blob pattern, so I can't tell
whether it's just a simple extension of the old patterns.
