News: APT Afterpay Ltd Says U.S. Sale Drove A 35% Increase In New Active Customer To Platform On..., page-6

You forgot to refer to the footnote 3. The 35% increase in active customer is in comparison to what the event managed to do in the last Afterpay day sale in August 2020.
This is important because that's far less impressive than having a standalone 35% increase in active custo amers.

Either way, it looks like the sale event was a huge success. 6 million lead referral in a few days? Paypal how many lead ref... oh wait... it doesn't have a market place.
