On page 606 of the Pathfinder 2e Core Rulebook, the description of the Boots of Speed reads (emphasis mine):
[...] You click the heels of the boots together and gain the quickened condition for one minute. [...]
Further reading of the description of the quickened condition on page 622 states:
[...] Because quickened has its effect at the start of your turn, you don't immediately gain actions if you become quickened during your turn.
I understand all of this without issue. However, if the duration for the Boots of Speed is one minute (activating when the action to do so [clicking of the heels] takes place), then the duration would expire with only 9 rounds of actually being quickened.
Does the duration of the effect of the boots of speed delay or get stretched to allow for the 10 rounds that go by in 1 minute? Or does the player lose 1 round of being quickened?
