I've merged PS4/PS5 on the boards and they're now just labels instead being separated, unless there's a significant advantage on newer hardware, it's better to have all the runs grouped together as it looks much cleaner and everyone is competing with each other. This game wasn't given any enhancements on either the PS4 Pro or the PS5 and I looked at load times across different consoles and the difference was negligible.

If a significant advantage is found then this change can easily be reverted. Both PS4 & PS4 Pro are limited to the same storage options. If there was going to be any advantage then I'd have expected it to be with the PS5. Sony allows users to install compatible storage options of their choice which does include SSD's for PS4 consoles so no system will be exactly the same.
