Profile. Don't speculate.
How many addresses have ever been added to that mailing list?
How many addresses had to be forcibly removed because they went bad?
How many deliveries would you have made to the bad addresses if each one
had stayed on the mailing list for a month after going bad?
How many deliveries have you made, total, to that mailing list?
