"I'm not looking for tax advice."

You don't ask peer users what to do with something that is wrong, that will continue to make it wrong.

You seem to have used "our determination of how long we intend to keep this" and not IRS Useful Life for the type/class of asset. That's what is being explained.

If you bought commercial real estate and you knew you would outgrow it in 5 years, you would never depreciate it over 5 years. That isn't what the IRS regulations direct.

You made this same error. Everyone is explaining you should fix your error, not try to compensate per your own plan.
