- JdeBP 1y agoA person with two watches finds xyrself suddenly in the messy business of doing full NTP, rather than the much simpler model of SNTP. (-:
- nullc 1y agoA person with three or more watches knows what time it is in proportion to the square root of the number of watches.
- stinkbeetle 1y agoA person with four watches knows what time it is in proportion to 2?
- dspillett 1y agoSort of. With two watches your confidence is ~1.4 of an arbitrary measurement, with three it is ~1.7, with 4 ~2, etc. Though this is an ever-growing sequence. A better model might be to measure the confidence with something like (x-1)/x as this grows, more slowly with each step, towards 1, without really getting there until infinity. With two watches you are 50% of maximum confidence in your time, with three 66%, with four 75%, five->80%, and so on.
- ofalkaed 1y agoIf you actually care about what time it is you need at least three so you can average them and knock out the error. The Beagle carried 22 when it also carried Darwin, in the nearly 5 year expedition they only lost 30 odd seconds.
