yeah I don't know why they can't estimate more accurately.
I wonder if it's a timing issue especially with ANZ, WBC and NAB payments due on 1, 4, 5 july. (last year was 1, 2, 3 july instead). So maybe this year WBC and NAB are out in 3q instead of 2q, whereas last year they were all in 2q. I wouldn't be rushing to conclusions on the quarterly dividend due to these effects
