The current description of the container.acquireStorage() method says "(only 10 queries/5min)", but in actuality 10 calls to container.acquireStorage() can be made and then a 5-minute cooldown is initiated, no matter the spacing of the calls.
It would be much more beneficial to lua coders to have it be a max of 10 calls in a 5-minute rolling timeframe, rather than the ability of making 9 calls (either spaced out or in quick succession) and then having the 10th (no matter how long after the 9th call) trigger a 5-minute cooldown. I imagine the idea was to prevent the use of container.acquireStorage() from being spammed, but even if you make 9 spaced out calls, the 10th triggers the cooldown and breaks any subroutine you may have had going at the time.
