But the daily diffs suffer from potentially missing data (which has only 
been solved by the minute-replication diffs). Only downloading the full 
planet will make sure that you're not accumulating "holes" in your data 
set.

And if you are content with weekly updates, then waiting one more day 
for the planet file to be ready doesn't really make a difference.
