Each leg is this way for us. Makes it so our trips can sometimes end up paying a fair amount more than they were originally blocked for, but never less.

However, Compass cancellation policy only covers the original trip block value. Say you're on a 4 day trip that's originally blocked for 22 hours. If you've racked up an hour in the first 3 days of a trip by overblocking some legs (ATC delays, waiting for a gate, etc), but underblocking others (you still get paid the original market block) and then a SFO turn cancels, you lose the 3 hours or so of pay that you would have gotten for doing that turn. So instead of getting paid 23 hours for the trip (due to the overblocking on previous flights) you'll simply get the trip guarantee of 22 hours (due to the canceled flight), unless you overblock so much on the rest of the trip to make up for the entire canceled turn (but that's pretty unlikely).
