Becker had a lot of opinions about atomic time, and he laid out
the pictures of just how bad things were.
Note figures 4 and 5

Those show how the rate of TA(BIH) was way off as of the 1969
rearrangement that did not attempt to constrain the frequency of the
new scale, and they show just how much the lack of air conditioning in
the USNO clock house was messing up the HP units.

Those artifacts of rate problems affect TAI forever inasmuch as they
mean that the supposed 1958 origin and the actual 1961 origin do not
correspond to the number of elapsed SI seconds in the value of TAI.
