If you can explain why those in your 'backyard' didn't
have to be exact as late as in early Modern Age,

Walls are built using standard bricks. These are not
identical due to manufacturing tolerances. The length of a
wall is calculated by the number of bricks in a course,
variations in size are taken up by mortar. Builders put
far more effort into ensuring that each course is level
than worrying about the exact length.

Your opinion. Not the one expressed by builders.In other words, you are saying that standard bricks are in fact identical
and mortar doesn't have to be used to make up for variations in size.

Just a moment.
A minute later:http://www.archifacts.co.uk/html/SitePracticeConsiderations1a.htm
"To achieve good-looking brickwork, particularly around openings, setting
out of the brickwork needs to take into account the variation in brick
dimensions which can be expected. The size tolerances allowed mean that
the actual size of bricks produced to BS 3921 will range from a little
larger to a little smaller than the standard dimensions of 215 x 102.5 x
65mm (the work size). To accommodate these variations, setting out should
be based on the co-ordinating sizes of 225x112.5x75mm (215 x l02.5 x 65mm
work size + 10mm nominal joint ). This procedure allows vertical perpends
to be aligned throughout the wall because the mortar joint width is
adjusted in line with any variation in the brick size. In addition, as
average sizes may vary within BS tolerances from delivery to delivery, it
avoids problems which can occur if brickwork is set out using the average
actual size of bricks in the first delivery."

Either you can't understand what Ken has written (just as you completely
misunderstood what I wrote), or you are making it up as you go along.

Does she understand the tower is made of fieldstone? That its
dimensions make it oval in shape? I posted an architect's critique of
the tower, including construction needs and man power. No bricks.
