The setup time is not an issue to me and thus should always be not voted on or pulled out of the poll.
I use the five of the 7 minutes to get a drink, take the trash out, check info, watch tv, do chores, take a d. etc.
5 minutes would be ideal as setup.
I think your buffer time is too high, and as MGuy says having to wait out an abandoned game when the player does not leave and just sits there and scoffs at you. It would require dollars to be input into programming a "report this player" or like he says a 2 minute must move. The 2 minute rule could be that same 2:30 timer that starts to run when a player actually leaves the site as it is now. The site doesn't need to know the difference between a discoed player and one who sits, with a 2:30 must move rule. 2:30 is not enough time for my computer to reboot, I need 4.5 minutes anyhow. Yes I left games being a poor sport, but it does not hurt my feelings when it is against me I smile when they run, it gives me time to refresh my drink. And of course I don't care if someone tells me my mom is a witch.
If you want to remove the burden off of each of us to take screenshots to prove draw refusals you have to lower the FREE time significantly less than 10 seconds, and eight seconds is way to many to reduce that burden.
HOWEVER#1. If you are fine with taking umpteen screenshots and losing time in getting mspaint up and typing this and that to your opponent and clicking fast enough so that the timer doesn't run out on you while you're being a policeman to offset the inept baby that programmers gave birth to, and instead want to speed up games just so you can get them finished and get on with your day, in a fair amount of time, then at least lower the FREE time to 8 seconds and leave the BUFFER time at 5 minutes.
HOWEVER #2 If you instead want to speed up games so that slow play is not rewarded, and fast play is rewarded then lower the FREE time to 4 seconds or so and raise the BUFFER time to 10 minutes. I am not an ISF fan, so just because I say reward fast play that doesn't mean abiding to ISF timers is an end all. Instead punish deliberate slowness that 7 out of 10 times is not used to apply intelligent moves, it is instead used to annoy players who have other things to do in their day. Not one person who has played here 200 games, needs 1 hour of "thought". The deliberate slowness is to make the other player make hasty decisions only because they can't afford to be on the site forever. I am not a fan of scottrussia either, who wants to blow his wad in 2 minutes 15 seconds, I appreciate 90 minute games.
So unsportsmanlike draw refusals aside, a 4 second FREE time combined with a 5 minute timer will make the game to challenging for many, but a 5 second timer and a 10 to 16 minute buffer time will force those shufflers into more meaningful a tad quicker decisive moves that help the game, but not at the burden of making them make bad decisions, rather make them make careful but meaningful moves that move the game forward
