Tournament will typically end no later than L16/L17, or approximately 4.5 hours (including breaks) when using 15-minute blind levels. Using 20-minute blind levels will extend total tournament length to around 5.5 hours.
You can also run the event with larger T150K stacks (300BB, 8/11/12/3) and no re-buys, which adds roughly 1/2-hour length to the above times (should end no later than L18).
