Regarding your comment earlier in this thread : "The estimates are based on the assumption that a measured hour after boot will be maintained every hour the box is on. Once the epg is there it's there"
My original tests seem to suggest the data rate remains high because for the data below the box was powered up around 19:35 and left on all evening.
13/12/12 19:00 - 20:00 - Up:0.79MB / Down: 23.45MB
13/12/12 20:00 - 21:00 - Up:1.47MB / Down: 44.29MB
13/12/12 21:00 - 22:00 - Up:1.49MB / Down: 42.65MB
I'm going to do one more test and leave the box on overnight and see if the usage rate continues.”

Paul my tests today confirm your original post

See post 22.
Around 43MB for every hour at least over a 2hr period.
Interested to see if it's linear. Suspect it will be, done everything I can think of to test,
The download appears to be in discrete chunks.
eg
2 mins 2MB, 4 mins 2MB, 5 mins 3MB, 10 mins 3MB, 11 mins 6MB and so on.
What I don't have a clue about is if this amount of data is actually needed or could be reduced without affecting performance.
Why freesat would transmit more data than needed is hard to explain (it must cost more in the long run to do so)
Freesat may be between a rock and a hard place.
On one hand they get stick for taking a while to get recently aired programmed onto the catch up epg and on the other hand for continous data updates.
Repassac thinks it may be image related content for Showcase. May be, but the amount of data for relativelly small still image files seems unlikely to me.
