| 0935 | Fill LN2 cold trap full. |
| 0936 | Open V6 → 13.6%. Condenser pressure decreasing slightly to 72 mbar, probably due to the cooling LN2 trap. |

| 1412 | Open V14 to let remaining mix into circulation. Condenser pressure starts rising. |
| 1433 | Condenser peaked at 220 mbar, now at 207 mbar. P1 = 0.9 mbar. 1K pot = 1.5 K / 6 mbar. Tower = 127 mK |

| 1607 | Close V14. P1 drops from 0.11 mbar to 0.036 mbar. Maybe there was still some mix coming out of the dump? Looking at P1's pressure history, it does seem that it hadn't quite settled yet. Re-open V14. P1 returns to 0.10 mbar. |
| 1623 | 1K pot = 1.54 K / 7.0 mbar. Open 1K pot needle valve +10 degrees. P2 spikes to 110 mbar before oscillating about 25 mbar |
