I do not know why any player times out on any round they play,but I have played many that just do it just because they can and do not care about making others wait on them,or they have another window open and are looking at or doing two things instead of just playing the round..I have seen many on a round let the timer go down to under 10 seconds or less this includes legends,also many players will wait till their turn before they even attempt to plan the shot out and at that time use the tools to help decide where they want to put the ball,Why not do all this homework while the others are doing their shot or shots,then when it is your turn you know where you are going to hit the ball..then tee it up and drive it...it is simple..I do like a well paced round..not one that is not totally fast...but not one that is totally slow either..and pretty sure most players feel the same way.
I do not ever expect players to play the same way as I do as we are all different and that defines who we are and is great...but when I stand on the tee I know already where I am going to put my ball and can take the shot fairly quick,,but this does not mean I want every other player to hit it as fast as I do...but I do want them them to hit it in a respectable amount of time not say 50 seconds out of a 60 second timer and I do realize some do take longer that are lower tiers players but still should be able to hit the ball in a decent time frame if the shot is already planed out before their turn,also if for what ever reason you are going to quit a round..be considerate and go threw the menu and forfeit the round even if you have to wait till your next turn..players to not like quitters but dislike them even more when they just click. ..X...and then do not even bother to return to the round
