Actually, JS never claimed that he was audited by Berkower. In 2019 he and Berkower signed a letter of engagement to audit their 2020 numbers, and thus they were allowed to list Berkower as their auditor on their FactSheet, PPM and from ADV. At the start of 2021, JS decided not to complete the audit. The FactSheet that contained Berkower's name was from the start of 2021. As far as I can tell, there were no lies or deception.
Furthermore, all of BB's performance figures are calculated by their 3rd party admin, not by JS as. DL would like you to believe. That's how you know his numbers are legit. The auditor is not needed to verify the accuracy of BB's performance.
