Yesterday I did my first adjournment. Time control is 40/90, SD/30;+30. Move 107, IM has K+Q, A player has K+R+P. Game had gone from 10:00 to 3:45 with the last round at 4:00. The players had no idea what was going on. They played thirty more moves after they finished their fourth round games before the A player got snap mated, but in a lost position.
Is the point you are trying to make that you prefer d10 over inc30 since you don’t have to worry about a long game affecting the start time of the next round or adjourning a game?
