Depends on the category. If we were to do "Get the Pearl" it'd be very bad once the stamp for "Time Trials" modes already instigated many people to speedrun it, so in my opinion that's quite a bad speedrun. Nevertheless, compressed air mode run and pearl run could happen I guess. Another idea is to speedrun all the levels of Aquagrabber (e.g. pearl, no stubs lost, black pearl, time trials and compressed air mode), and the soda seas speedruns would also be very interesting. What's bad about Aquagrabber is that it's a bit arbitrary and unless some runners come in agreement to which categories we should do I won't be making them now.
So short answer yes but we'd need to set it up. If we do, we'll probably bring it to the main boards (https://speedrun.com/cpr)
