Hey NicColt, 1*2^28 is the smallest amount of work you can have in a packet, it's also better known as a block (or lately a Stats Unit) if you're constantly doing these you'll have much more network traffic, our 
faQ on the subject recommends using a packet size of 33 in the .ini so your client tries to get 32*2^28 packets instead of 1*2^28 the first one obviously contains more work, but the stats'll be the same you'll just have to wait longer for a packet to finish 
 
This is what you're going for in the .ini:
[rc5]
preferred-blocksize=33
fetch-time-threshold=336 (the number of hours in two weeks)
if you do that you'll be set to stay away for two weeks 
 
Good luck
With love and respect your fellow TA member
