There’s no link, so I’ll explain briefly. Movement Points (MP) range from 1300 (with a speed of 1) to 2000 (with a speed of 11 or higher). It’s calculated based on the lowest-level unit. Artifacts that increase unit speed in battle (Amulet of Swiftness, Ring of the Wanderer, Cloak of Speed) do not affect movement speed. Speed artifacts (Boots of Speed and Rider’s Gloves) provide 600/300 MP (SoD) or 400/200 MP (WoG/ToTE), respectively. Logistics adds 10/20/30% MP to the base speed (excluding speed artifacts). In SoD, logistics heroes (Kerr, Gunnar, Dessa) receive a 5% bonus to their logistics level. For example, Kerr, at level 10 with a boosted angel, gets 2000 * (1.3 + 0.15) = 2900 MP. At level 20, it’s 2000 + (1.3 + 0.3) = 3200 MP. In WoG, logistics heroes receive almost no bonus. Stables add 400 MP. The swamp penalty is 75% (meaning the hero moves at 25% of their MP, or 4 times slower), snow and desert are -50% (2 times slower), and rocky terrain (barbarian lands) is -25%. The Pathfinding skill reduces the penalty: basic pathfinding eliminates the penalty on rocky terrain, reduces it to 25% on snow and desert, and to 50% on swamps. Advanced pathfinding reduces the swamp penalty to 25% and eliminates penalties on other terrains. Expert pathfinding or having only creatures belonging to that terrain in the hero’s army eliminates the penalty. That’s the gist of it. For WoG, there’s also a class system that provides additional MP.
