Remember, this isn't overall timekeeping, just sub-second
timekeeping. Running at half-speed for 10 seconds just means you'll be
off by as much as a second during that interval, not that you'll
accumulate overall drift.
i understand that. i just don't see why it's even remotely
acceptable... acceptable in that we say "don't fix" rather than
"fix, but it's not really a big problem."
(i'm not sure i understand your 10 second comment. if the cycle
calibration is going to be increased from 1 second to 10, won't
eg a banias 1.4ghz running a 600mhz be about 6 seconds wrong at
the extreme?)
