So the remaining question is: Is there any reasonable rewording of the
"old" title and comment of https://oeis.org/A172265 matching the terms of
this sequence other than "partial sums of A024820", which indeed is
"Number of roots of sin(1/x) = 0 in interval 1/2^(n+1) < x < 1". I have
added this as a comment in https://oeis.org/A024810 together with an
illustration.
