You can change the time between snapshots. I will try to make this a
configurable property, but for the time being you can edit
pimki/libraries/madeleine_service.rb and change SNAPSHOT_INTERVAL to
each hour. You will need to restart Pimki.
I am not sure that this will help with the missing data though :(
