Thanks for the explanation. I was just surprised given the large(-ish) size of some later armies that I saw (but luckily didn't have to fight) recently.
and sorry for the confusion.

If you consider say pikemen, the pike in a medieval army are exactly the same in game terms as Alexanders pike and thus cost the same. If Medival pike fought Alexandrians with the aid of a time machine it is probable that the medievals would win because of steel armour etc. but in the game they are both just protected average pikemen.
Undrilled superior armoured cavalry lancers are 16 points each and undrilled superior armoured knightly lancers are 20 points each.
That is 25% more per base so you will have less knights.
100 years war longbowmen are much better than the run of the mill archer but cost upto 50% more.
