You can mathematically prove that an exponential backoff is the

They do, and more recent routing technologies actively punish people
who are using excessive percentages of the bandwidth - the internet
routers are turning into traffic cops too

The maths is clear. And if your ISP is slow and you get heavy packet
loss and long delays from many sites (ie its not their end) then
change ISP. Vote with your feet.
