Remaining flight time prediction working. Ready for simulated profiles.

Reorganized EEPROM addresses in test mode to not disrupt the Excel.

Fixed missing "false" flow indicators.

Step to record in NVM sample index that marks the sample rate reduction.

Pressure change rate + its variance as conditions for landing detection. In the current state, the program works fine for tests in the glass jar (thus, expected to work for short quick flights), but it is using 7966 bytes from the flash already.

Average pressure change rate based variance calculation is ready.

Preparations for flexible sampling rate implementation. TESTS OK.

Strategy for parachute descent detection and sampling rate reduction.

Fixed landing detection condition to be just "variance < value", since variance can never be negative.

Updated Main Flowchart with method to calculate Initial Ground Pressure and Landing Detection based on 20 raw pressure samples variance.
