Are you sure you understand 'wash sale' rules?
you state you NEVER repurchased the security and if you look closely at my example, your tax loss across the multiple lots is correct at year end!
as @fanfare states and my example shows, your cost basis is adjusted upwards but since you no longer own the security, it all 'washes' out and you are in the same tax loss position! LOOK AT MY EXAMPLE CLOSELY.
