The shearwater sample rate is hardcoded to 10 seconds. So I don't see
how that can produce unexpected results. Or are you referring to the
reported dive time?

Last week, I merged a change to disable the ppO2 samples if all
(calibrated) sensors have the factory default calibration value (2100).
If you happen to have a unit that doesn't store the calibration values
properly, then this could explain why you are no longer seeing ppO2
samples with the latest libdivecomputer.

There is something strange with this data. The model number is zero,
while it's supposed to be 2 for the Predator. The number of sensors is
1, but none of the three sensors has its calibrated bit set, and all
three calibration values are also zero.
Does the rest of the data looks good, or are there other errors as well?
