Agree this, one thing puzzles me is, item 5.1.20 of processing model in [1] describes, a temp buffer should be used to collect beyond limit timing entries, while nothing related mentioned in section 4.
I've raised this issue to web perf group, unfortunately no feedback.
my preference is drop the beyond timing entries as honor user's choice.
