I don't know who this "we" is you're referring to, but I demand not to 
be included in that set.

No, I don't note that the left end of the histogram should automatically 
be the left end of the data --- not using that binning function, anyway.

To see what actually happens, plot your data modified by your binning 
function, but without "smooth freq":

# Curve 0 of 1, 20 points
# Curve title: "'mydata.dat' u 1:(bin($1))"
# x y type
  1120  1049.25  i
  1160  1049.25  i
  963  699.5  i
  1546  1399  i
  258  0  i
  964  699.5  i
  1128  1049.25  i
  1169  1049.25  i
  1007  699.5  i
  259  0  i
  179  0  i
  1408  1399  i
  1207  1049.25  i
  1389  1049.25  i
  308  0  i
  1179  1049.25  i
  147  0  i
  508  349.75  i
  1148  1049.25  i
  1308  1049.25  i

Note how the actual lower end of those data is not 147, like you think, 
but 0.  Same goes for the upper end.
