If you play around with numbers you will notice that for most encodings 
with a ratio greater than 1/2 the big phase-shift in recovery 
probability happens around 50%.  Upping the numbers beyond 1/4 just 
makes this shift in the curve faster over a smaller range in recovery 
probabilities.  In the long term what is going to matter more is the 
peer redundancy rather than the encoding redundancy.
