Round table

Why are you doing these calculations? Does anyone in the game actually do this?
From experience, such decisions are usually made based on intuition, not mathematics. Once you have a general idea, all your calculations become meaningless, like trying to calculate an infinite number of Pi.

When playing in typical situations, you naturally stop calculating and rely on experience. For example: Taras and a group of dwarves on level 111, with a standard stack of 31-34 wolves.
Minimum - the wolves take out 10 dwarves with one attack, and goblins are lost without any casualties.
15, 20 - after removing the retaliation, the wolves take out the stack in two attacks. In the 20th level, 1-2 dwarves might remain, with losses of 5 units.
Maximum - after removing the retaliation and activating the wolves, about 10 dwarves will still remain, so you need to attack with the wolves again. Therefore, you need to be more careful, and the wolves must have the opportunity to attack the stack of dwarves twice.
But this is the standard approach, and even the laziest player can do it.

But what about, for example, the Miner, if he finds a level 2 resource and has several trog nests? In the minimum difficulty, anyone will rush in without thinking, but in the double difficulty, with reduced stacks in the town, they will give you a hard time. At the same time, if there are 2-3 trog nests and Shakti is strong, there is a temptation to go there, and in this case, it is simply necessary to estimate the numbers, because the battle will be close. You can, of course, rush in blindly and then ask for help, but even the Samurai has long since overcome this habit.
