Managing Slow Play
At our various congresses we have a pair who are notoriously slow, often being a board behind everyone else at the end of a 7 or 8 board round.
I can (and do) take a board off them, but that can be unfair to whoever they're playing.
I can of course award 60/40, but I need evidence that one side is at fault, and "it's always you" doesn't really count. If I instead award 50/50, their opponents will often (quite rightly) complain.
So I wondered if this would work as a condition of contest:
"Any pair consistently in the last 5% to finish a round will be deemed to be at fault if a board is taken away in any round through slow play, unless the Director determines otherwise."
Thoughts?

Even without a regulation/condition of contest, you can use the evidence from one round to decide that they are wholly at fault for running out of time in subsequent rounds.
Really?
That makes things easier!
