Incremental Times

[David G Congalton]

There are enough for a small congress. Some clubs (Hamilton and EK for example) might be willing to lend others.

What is a small congress? If not enough clocks were available for a larger congress, would it be best to forget the incremental idea or have sections with different time controls? If the latter, which sections use which time controls?

90 mins with 30 sec increments gives 60 moves in 4 hours and 90 moves in 4.5 hours and was one of the 'recognised' time controls.

So, just so I'm sure, the time control quoted on an entry form could be 60 moves in 90 minutes, with a 30 second increment from move 1, followed by 30 seconds increment per move? Is this okay for grading and would it be acceptable for a FIDE rated event?
