trust the stats, they reflect what is in the unit.txt file that determines their combat attributes.
on an related note, i was wondering if the Massilian Medium Infantry are supposed to have only 60 men (on large setting). just seems a bit odd since they are nothing special combat wise and they have quite a high upkeep per person. other units which are of comparable strength generally have 80 to 100 men, for example, the greek outrunner hoplites are very similar and have 100.
edit- they also take 2 turns to create.
