Richard questioned a 4e-9 pressure rise when we heated up OM2 in June 78573 (plot). The first time we heated OM2 after the O3/O4 vent in November 2022 (plot) the spike was larger 9e-9. Future times we heated up OM2 in O4a (July and September) the rise was smaller. 

Keita says that it is expected that the first time you heat something up after a vent the pressure can rise as particles from venting are burnt off, future OM2 heating we'd expect smaller pressure rises.
