Agreed when you are below 16-man or smaller pools the reduced time will greatly help.
When I was assessing this as a mathematician, I used a baseline of 16 teams with full brackets and an average match time of 4 minutes. I figured that was reasonable for a worst case. Any byes and fast pins will reduce that average time but the first two rounds will still have 8 matches per weight and take will over an hour. After that it accelerates.
