4 * 9.5 * 0.05 + 0.2 / 3.2 * 4 * 9.5 * 0.95 = 4.15625s
after initial application whereas according to Hypothesis 2, the aura should last only 0.2 / 3.2 * 38 = 2.375s
after initial application. Taking into account hitlag extension for elemental auras, the aura duration observed in the video matches Hypothesis 2, not Hypothesis 1.
