BLITZ TOURNAMENT

Kirr is a Ranger. His native land is "grass." The starting army of 1 Centaur provides a speed bonus of 6 points, which is 1700 movement points. The Logistics skill provides a +10% bonus, and the specialization provides a +5% bonus, totaling 1955 movement points!

The calculation is not entirely correct, as the +5% should be added to the 10% bonus from Logistics.
As a result, we get not 15%, but only a 10.5% bonus...

THE PARADOX IS THAT ONE CENTAUR IS A PATCHED BUG FROM ERAFIA (where when you buy a second hero, the army is full, and therefore there can be Gnomes), BUT THEY PATCHED THE ARMY, BUT NOT THE HERO'S MOVEMENT :D

By the way, you are right here. This is most likely how it works. The starting army plays no role because the movement is set in the core by default and is not recalculated... that is, each hero has a strictly fixed amount of movement at the start, regardless of the army or the castle in which he is hired... How he spends this amount is another question. Here, terrain penalties or bonuses come into play (if it's a road)...
