Did the same for the JSON file from my Buddy who uses the Suunto Ocean and was making the same dive with me that day… These are the reults.
Claude.io: This dive’s data is much cleaner than the previous one.
Here’s what I found:
Dropout rate: 3.6% (much lower)
Only 13 of 360 gas-0 readings have missing Pressure/GasTime, spread across 9 short episodes — 7 are single-sample blips (0-1s), the longest are just 2 samples.
Compare to the earlier dive’s 26.3% dropout with 43 episodes — this transmitter connection was far more stable.
Startup ramp-up (expected, not really an anomaly):
The first ~5 samples show GasTime/Ventilation as None (not 0) while Pressure is already valid — the computer hadn’t accumulated enough breathing data yet to compute a rate. This is normal startup behavior, distinct from the mid-dive zero-dropouts.
Right after that, GasTime hits a flat 6000-minute ceiling for 3 consecutive samples (08:54:19–08:54:39) — an unrealistic 100-hour “time remaining,” clearly a display cap/sentinel value used while the consumption estimate is still very low/unstable, not a real prediction.
A genuine (non-error) exertion spike: Around 08:54:59–08:55:39, Ventilation jumps to ~0.0004–0.00044 (roughly 4 std devs above the dive’s mean of 0.000176) for 5 consecutive samples, and GasTime correspondingly drops sharply (5166 → 4085 min).
This lines up physiologically — harder breathing → faster projected gas depletion — so it looks like a real brief exertion event (current, effort, etc.), not a sensor glitch.
Minor sensor noise:
Pressure “increases” slightly (rather than only decreasing) at 36 points in the dive, but these are tiny — averaging ~13,000 out of readings in the ~7-20 million range (~0.06-0.1%), consistent with normal transmitter/quantization jitter rather than any real gas refill.
No negative values, no NaNs, Ventilation and GasTime otherwise stay in sane ranges (1278–6000 min, 0.000096–0.000442) for the full 57-minute dive.
Bottom line: this dive’s transmitter link was solid — the only real data-quality flags are the brief startup-ramp None/6000-cap period and a handful of tiny pressure-noise blips, nothing like the recurring false zero-outs from the other dive.
