Domain Leakage Examples and Statistics

[Singularity Domains]

Outside of O.co's self-confirmed 61% leakage to O.com, what are some other quantitative examples of non-.com's loosing traffic to the corresponding .com?

My interest is actually a little more specific than that as the situation I am currently discussing with a customer regards leaking [name].cctld to [name][cctld].com where they chose the cctld because it represents an abbreviation related to their services and not for any geographical reasons. I am guessing data and probably even anecdotes for this kind of leakage is much more scarce, though.

Thanks in advance to everyone that has something to contribute.
