Original release notes

【What's New in This Update】

■ Redesigned CCF Calculation Logic
CCF (Chest Compression Fraction) is now measured precisely from the moment
of patient contact. On the results screen, your actual CCF is shown side
by side with the theoretical maximum CCF determined by the delay before
your first compression, so you can compare the two at a glance.

■ New Worst-Interruption Ranking
Automatically detects interruptions over 10 seconds and ranks them by
duration. Linked directly to your procedure log, so you can pinpoint
exactly when compressions stopped and why.

■ Full-Screen Landscape Graph
View your training graph in landscape, full-screen mode for a more
detailed look at the full session.
