You also used a neck weight and had the weight of the mono too this would have to be a few kgs.

For my last breath, I exhale fully, then relax, at which point my lungs auto-inflate to FRC volume. I then take a tiny extra gulp on top of that. The main reason I do that is because while floating in the water, my chest is a bit compressed, so I need to gulp a bit extra to make up for the compression. Anyway, my dive performance doesn't seem to change much whether I dive on actual FRC, slightly below, slightly above, etc... I can even do 100% exhale recreational dives for about 1'20" once I get in the zone.
