In EDU.txt, there is a list defining what the different unit combat variables are.
In particular, for STAT_PRI & STAT_SEC, there are 10 defined but actually 11 are present in any given line.

For example, ROMAN PRINCIPES have the following:
stat_pri 12, 6, pilum, 38, 2, thrown, blade, piercing, spear, 20 , 1
AND
stat_sec 11, 6, no, 0, 0, melee, simple, piercing, sword, 0 , 0.3

BUT, THE VARIABLES ARE DEFINED IN THE PRE-TEXT AS FOLLOWS:
; stat_pri From left to right:
; attack factor
; attack bonus factor if charging
; missile type fired (no if not missile)= arrow, javelin, bullet, stone, pilum, bamboo_javelin
; range of missile (in meters)
; amount of missile ammunition per man
; Weapon type = melee, thrown, missile, or siege_missile
; Tech type = simple, blade, archery, siege OR other (elephants only)
; Damage type = piercing, blunt, slashing or fire. (I don't think is used anymore.)
; Sound type when weapon hits = none, knife, mace, axe, sword, or spear
; Min delay between attacks (in 1/10th of a second)

It seems that one of the last 2 values is "Min Delay between attacks..." and the other is something else.

(Q1) Which of the last 2 values is "Min delay between attacks (in 1/10th of a second)"
(Q2) What does the other value represent ?

Much appreciated is anyone knows this.
