Hello,

The system (at the moment) is sensitive to the size of outgoing packets; the
bigger packet size you ask for, the more it costs (this is explained in
https://atlas.ripe.net/docs/credits/).

I suspect we'll need to review that, as this seems to be a recurring issue
for users and there's not that much difference between a 100 byte and a 1000
byte outgoing packet. The costs should be more related to the number of
packets and less to their size.
