Lower F
Example: FM1 (Z-fold)
First, compare the L2 measurements.
In this example, imagine that L2 is longer at the front than at the rear.
Look at the table, in the row for FM1, and the column for L2.
'F Long' means Front measurement longer than Rear
'F Short' means Rear measurement longer than Front
L2 is longer at the front, so we have an 'F Long' situation.
Then look at the next line, below 'F Long'. It says 'Lower F on S2'.
