@WarnerCrocker Variables I'm guessing might come into play:
Practice - maybe I use it more than most and have gotten better at how I ask questions? But examples I gave in post are pretty much what I ask Siri so fairly straightforward.
Devices used? Maybe some are better than others? My least used is HomePod, most is iPad and iPhone.
In general Siri hears and interperpates my questions accurately and as noted, the responses are usually on par with what I hope for.
