You are supposed to keep three counters for the number of each ECT(0) and ECT(1) and CE mark reported so far on this connection (for this ack space). Increase means the difference of the count reported in the latest ACK compared to the current local counter value. Total increase is increase of ECT(0)+increase of ECT(1)+increase if CE compared to local current count of ECT(0)+ECT(1)+CE. Does that help?
