I don't know.....you got to figure that the 1's are much slimmer than the 0's.
I would think that them fat 0's would weigh more...LOL
Ye gods some people don't have common sense. The 0's are hollow and whats more they are more aerodynamic when they flow through the computer. Whilst the 1 has a hooky bit on the top and catches on everything. That's why the files with more 1's are slower.
See you learn something everyday.
