BLITZ TOURNAMENT

The following factors can change the speed of units: artifacts, the presence of native land, and specialization. (The resulting speed is indicated in parentheses next to the base speed)... However, changing the speed of a unit does not affect the speed of the hero.

The speed of warriors, increased by specialization, increases the speed of the hero. Try it yourself.
By the way, the logistics calculation seems a bit strange. Specialization still gives a bonus of 15%/25%/35% to the hero's movement range. In my version, it's exactly like that. And it doesn't depend on the hero's level.
And according to your formula, the movement range (on the first day) of a hero hired from a tavern is calculated. After skipping a turn, the movement range is recalculated from the "Logistics" skill + 5% (15%/25%/35%).

I figured it out... :) Only the .xlsx file extension is not recognized. Excel should be in .xls format.

And it doesn't open? Try deleting the last letter:) .
