(1) 16 - starting time reserve
(2) 8 - time added each turn for running around the map
(3) 1 - time for a battle (if the battle is completed faster, the time reserve doesn't accumulate)
the time reserve (1) is spent on securing the map and running around (2) and battles (3); if a battle exceeds one minute
it seems this was the case a few versions of the HD mod ago
there are also persistent rumors that the chess timer is glitchy, and that work is constantly being done on it in the HD mod
p.s. and also - 1 minute per battle with a starting reserve of 16 is essentially a blitz game
Thank you. I tested it. I understand. It's a strange system, but okay.
