Here is the way to find out.  Log on to ICC and type "search crafty ban"

Here is what I found.  Out of the last 40 games, crafty won one on time, while
up material.  Out of the last 80 games played, that one win on time was the
only game that 'search' showed.  I assume he didn't lose on time _often_ based
on that, wouldn't you agree?

As far as time odds, your formula holds up for _any_ game on unequal hardware.
Which is well-known.  If a machine is twice as fast, it is twice as fast.  If
you want to call it 4.5x faster because it is twice as fast but time dilation
makes it look bigger, fine...

When I play 'time odds' games, and give my opponent 2 mins to 1 min on the
clock for me, I don't then explain to him that I am "really" giving him
4.5 to 1 odds...
