Summer Cup for HoMM 3 on the TE-lite version.

Considering that the generator and value of monsters in SoD and ToG are the same, it seems that there is a lack of observations. At 6000, 5th-level monsters appear quite often.

5th-level monsters also appear in SoD - they are weak, monks, earth elementals, and pit fiends. I haven't seen liches, minotaurs, cows, or djinn even once, and I'm not sure about barbarians. It seems that there are some limitations on specific types of monsters. 6th-level monsters and even some 7th-level monsters easily fit within 6000, but the generator doesn't use them in such passages. Perhaps these limitations differ between SoD and ToG, at least regarding the 5th level.
The rusty monster is unclear - a hive + 2 groups = 12000, and one rusty monster is 26000, which seems like a bug.
