iCloud polling and how the timing works

Can anyone explain the logic at work here?
What impact does the polling period have on the frequency of polling? Also how does the polling divider work?
I thought I knew, but actually watching Mrs C as she approaches it seems my understanding is deeply flawed.



look at the polling map/divider section of the first post.

Ta. Missed that.

I think I see what the issue is. Might have to go with a custom map
