Every figure is an output of your trace. Those marked TAPE were measured on the demo pond
and disappear once you trace your own.
The ledge is the hardest outline to trace, because a dug shelf grades softly with no line
to follow. On the demo it runs about 11% longer than the 121" tape, which would put the
headline near 205 gallons if tightened. It is published as drawn rather than nudged to make
the check pass.
