 It's interesting to see that according to the first measure, *the first cosmonaut wasn't really a discontinuity* (a deviation of 1 year from the predicted value). After Gagarin, one might think that it's not possible to reduce the time any further. Note, however, that sending a digital copy of a human through the internet might count. Also note that your definitions get in the way.
