The actual total supply of the token is random and depends on when _executeInflationRateUpdate is executed.
The README and tokenomic documentation clearly states that The token supply is limited to a total of 268435456 tokens. However when executing _executeInflationRateUpdate, it first uses the current inflation rate to update the total available before checking if it needs to be reduced.
Therefore if no one mints or calls executeInflationRateUpdate for some time around the decay point, the inflation will be updated using the previous rate so the  totalAvailableToNow will grow too much.
You should do
Only if the condition block.timestamp >= lastInflationDecay + _INFLATION_DECAY_PERIOD is false.
Otherwise you should do
Then update the rates, then complete with
Note that as all these variables are either constants either already loaded in memory this is super cheap to do.
