I can't imagine what this duty cycles about, for a power shower,
unless it uses all the hot water in 15 mins, and needs 45 mins to

An electric shower will give me a shower of unlimited length within
30 secs of getting in the door, whether the DHWs hot or not

And that is a selling point?!

Absolutely

You need an unlimited duration shower to deliver enough water to wash in.
