I couldn't. Also, I said I didn't buy it that all BWF events should be slow venues. But the shuttles are apparently the same in those events. And, as you indicate, going back in time at looking at results may not be fair for such an analysis, since the scores don't show all the other external factors. But there is a tendency. And knowing the nature of a venue while watching the match, you can also see it. Even on the TV.
