We consider the preferred turn time across the entire HoMM3 forum to be the arithmetic mean for each template group:
the sum of the additional day times multiplied by the number of voters for each / total number of votes.
Rounding to 30 sec.
As a result, we get the average turn time:
on XL+U templates - (487 sec - 66 votes) - 8 min
on JC XL-U template - (505 sec - 63 votes) - 8 min 30 sec
on Diamond, Mini-Nostalgia, Anarchy - (480 sec - 64 votes) - 8 min
on 2SM4d(3), balance, Panic - (385 sec - 67 votes) - 6 min 30 sec
Overall, the results are predictable.
And here is the correlation:
1. On Jeb, the battle time turned out to be the longest (1.5 min), and the turn time shifted toward a decrease compared to the seasonal SoD timer (10 minutes).
2. On sm, conversely, the battle time is 1 min, while players require more for a turn than the current seasonal SoD timer (6 minutes).
All that remains is to determine the starting time. I will create a poll — the link will be here.
