0. Store previous cycle's drain decision in integral (l) memory.
1. Fill to A trigger (use all places below 1-10).
2. Boil to C trigger without timing to allow previous fill water to mix thoroughly during boiling.
3. Boil from C to D while monitoring time (T actual).
4. Decide how long (how much) to drain, then fill to B.
5. Drain according to the P+I calculated drain time, fill on to control outlet temperature.
6. At D, stop draining and postpone remaining drain, fill to B.
7. Continue remaining drain.
8. With drain finished, fill to A.
9. Boil to D, timing from C to D.
10. Decide how long to drain (in this case zero) based on present and past cycles.
