> The optimization takes the execution from ~6300ms to ~4500ms on my machine > (representing a 28% - 39% improvement depending on how you calculate it) The correct answer is 28%, which uses the initial value as the base: (6300-4500)/6300 ≈ 28%. You are starting at 6300ms and speeding it up by 28%: >>> 6300 - 28/100*6300 4536.0 Using 4500 as the base would only make sense if you were calculating a slowdown from 4500ms to 6300ms: we started at 4500 and *increase* the time by 39%: >>> 4500 + 39/100*4500 6255.0 Hope this helps. ---------- nosy: +steven.daprano _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue43014> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
