Answer to Question 1

The reference point for measuring the height above the table must be chosen in such
a way that elongation of the spring is the variable that is consistently measured. This
measurement may not be consistent if the masses vary in size or if the bottoms of the
masses are used as the height reference point.

Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
