From the data below, ClockKit generates future `CLKComplicationTimelineEntry` items once, but for past points in time, 24 calls are made! Why is this?

**More details:**

I'm noticing a curious behavior in my Apple Watch complication.

It supports Time Travel -- I supply data for 1 day past, 4 days into the future. I'm currently trying to be a good citizen and make fewer calls to regenerate my complication data.

To get an idea how often certain calls are made, I put a simple `print` inside both `getTimelineEntries(for:before:limit:withHandler:)` and `getTimelineEntries(for:after:limit:withHandler:)` that outputs the `before`/`after` parameters.

When I launch the App/Complication in Simulator, I get the following output:
