The default Jebus timer is 24+8:30+1:30, and the timer in this tournament is 16+8+2. To compare them, we need statistics on the number of battles lasting longer than a minute and a half. Take a look at streams of mirror Jebus matches to get an idea of how many such battles there are and get a more accurate picture. I haven't calculated the exact statistics myself, but from what I can see, there are quite a few, so these timers are roughly equivalent.
Or, another example – in the current Mirror-2 tournament, the timer is 16+8+1:30, and it seems to me that mt-Jebus requires no more time (and possibly even less due to better skills) than h3dm1 or mt-Diamond.
Also, let's not forget that in HotA 1.5, mechanisms for accurately calculating routes have appeared, which, in complex scenarios, provide a noticeable time saving in calculating chains, so the same amount of actions now requires less timer.
P.S. Now I think that we should have made it 16+8+1, there would be just as much arguing, but more benefit.
