Assuming maximum drop in SO2 :

Simulation of free SO2 level after adding wood (mg/L) 0
Simulation of molecular (active) SO2 level after adding wood (mg/L) 0

Assuming average drop in SO2:

Simulation of free SO2 level after adding wood (mg/L) 0
Simulation of molecular (active) SO2 level after adding wood (mg/L) 0

Below 0.4mg/L of active SO2: maximum risk of spoilage microorganisms developing.
The SO2 content must be adjusted.
Between 0.4mg/L and 0.6mg/L of active SO2: potential risk of spoilage microorganisms developing.
Monitor active SO2 level and bring it back to a safer level if possible.
Over 0.6mg/L of active SO2: minimum risk of spoliage microorganisms developing.
The SO2 level is correct.

NB :
This simulator only displays theoretical losses due to wood porosity.
In practice, many other factors are sources of oxygen and cause sulfates to oxidize into sulfites: racking, pumping, micro-/macro-oxygenation, etc.
Wine composition (polyphenols, lees), previous oxygen supplies, and ageing conditions (temperature and how it varies in the wine cellar) also influence how wine reacts with oxygen supplies.
