Ugh, so I guess you are saying that derived properties are not

in this usage?
No, just that if you don't actually change the value, KVO might not
bother notifying listeners. The actual values are fine, just wanted to
address this issue in case you see fewer change notifications than you
expect in the course of your debugging.
Oh, OK. In my case, I don't need (or even want) a notification if the
value doesn't change, so even if the KVO system doesn't notify my
listeners in case of an unchanged derived value, I won't mind.
Thank you
