The main advantage of the Mini-Nosta is that it is easy to award. You look at the situation, and the outcome is clear. You estimate the time it will take for the fleeing player to finish their turn, you estimate the amount of loot that their opponent will gather during that time, you add it to the strength of the armies/heroes, and you compare.

For example, the Medium vs. Redwait game from the last CIS tournament ended with a mutual agreement to award the victory on turn 14, although there were still 2-3 weeks of gameplay left, but it would only have prolonged the inevitable.

But in 8mm6a, such a calculation is usually impossible - there are too many possible routes for the players, too many castles/villages, teleports, and so on.

Playing 8mm6a on L+U is just ridiculous, I suggest not considering it :)
