Usually the description of the time controls is simpler, like G/60,d5, and that I understand.

9-SS - 9 round Swiss pairings

40/80 - 40 moves in 80 minutes

SD/30 - Sudden Death in 30 minutes (the rest of the game after move 40)

d30- 30 second delay

Thank you!!

Does that mean each player gets 80 minutes for their first 40 moves? And does each player get 30 minutes after move 40?

Is the first 80 minutes use it or lose it? Or does it roll over into the time you have after move 40?

Each player has 80 minutes to make their first 40 moves. If a player oversteps that bound, they lose if the count is correct and the flag is called. If the time control is reached, then 30 additional minutes are available in addition to any time on the clocks already. Exactly how that is handled depends on the clock

Very interesting. Don't see this at any local competitions we go to, but this particular one is more of a regional/national meet.
