What does "cap" mean in
"So a two-week sprint would *cap* the sprint retrospective at an hour and a half"
"upper limit" as a noun
"set an upper limit" as a verb
So the first link says the 45min/wk rule *sets an upper limit* of 1h30 for the retrospective of a two-week sprint, and the second advocates an *upper limit* of three bugs per developer.
And in this
"For example, consider a bug cap of three bugs per engineer. "
