Thanks for trying to make continuous improvements.
But this feature only makes sense for the pool games, which is the only place (I think) where players can get a “surprise” start (because the time to pair is very indeterminate).
All other matches, as far as I know, require a positive “accept” response from both players for starting. No extra game time should be needed. (Player (or tourney admin) has the option to cancel the match if 2nd opponent drags feet excessively on the “accept” for non-pool games.)
Also, per other comments as well: What’s really needed for *tourney* games is the ability for any SINGLE player to start the clock/game unless the opponent has gone offline (maybe with up to a 20-second grace period, depending on the time control). Just as in OTB. It’s disrespectful to all the other tournament players to delay starting a game (makes round times less predictable e.g.). It’s not hard to keep track of a tournament round’s progress and to be ready at the start of the next round. The time penalty for missing the start (when your opponent hasn’t) should be off of your clock, not on the tournament round’s predictability. (Again, going offline is a different kettle of fish; doing that risks admin forfeiting you instead.)
