@Felthry I think it should, but microwaves can be janky. mine interprets 70% power as "turn on the emitter for 3.5s, then turn it off for 1.5s, then repeat." except it might be more like 7s/3s?
(ours also doesn't do any hearing for the first several seconds, so if you put something in for 10s ten times, you get drastically different results putting an identical thing in for 100s)
