@Cicily_aura Method A is correct. It measures the branch length from the attachment point on the main stem straight to the tip.
Method B starts lower on the trunk and includes extra length, so it overmeasures.
The atomic breath scene in SHIN GODZILLA (2016) is absolutely unreal. The way the beam erupts and bathes Tokyo in purple is one of the most jaw-dropping moments in Godzilla history.
