Suunto please do something about this. This is not an isolated issue or a faulty Nautic that needs to be sent-in for service, it is a issue in the current firmware…!!
See below the response from support, this cannot be true. Triggering an alarm is a serious situation and cannot be left up to the divers interpretation to wait for the stabilization of the calculation.
Initial SAC Calculation Phase
During the first 5–10 minutes of a dive, the algorithm calculates your breathing rate. A higher breathing rate or sudden depth changes during descent may temporarily reduce the estimated gas time, which can trigger an alarm before the calculation stabilizes.
