> ... leakage by timing side-channels depends in parts on how accurate your time-measurements are The rate of leakage from a existing timing side-channel depends on how accurate your time-measurements are; the presence of such a side channel does not. (Though one shouldn't discount the value of degrading a side channel from kilobytes per second to millibits per hour, even the latter will only protect a reasonably-sized private key for a decade or two.)
