Timing Diacetyl rest?

I don’t check the SG before raising temp for a D-rest. I usually go after 4-5 days or when the visible activity is slowing down. Usually I’m doing my lagers in the winter, ala old style in a water bath in my basement. Ice bottles if needed to lower the temp, and an aquarium heater for the D-rest. Works for me…
I’ve never detected diacetyl in any of my beers thank god, because I’m apparently sensitive and can pick it up in other homebrews and even some commercial beers when others can’t. And I Do Not appreciate it!

Any widely available commercial beer? Pilsner Urquell? I’m not sure I’ve really tasted diacetyl…butterscotch, buttered popcorn, sure but not in a beer that I’ve perceived.
