How to achieve 62.5 kbps LoRa?

I recently bought an E22-900M30S which uses a SX1262 chip. On the SX1262 product page it says it is capable of transmitting at 62.5 kbps using LoRa. However, by doing some math, I found out the maximum speed LoRa can go is around 37 kbps (SF=6, CR=1, BW=500). How can I transmit at 62.5 kbps? Am I missing something?

The SX16x radios support spreading factor SF5 which when using your tool doing some math will give 62.5 kbps for SF=5, CR=1 and BW=500.
