After unlocking it, the speedrun mode does all the timing for you. Plus the in-game timer of the speedrun gives definitive proof against potential splices.

So I should Delete normal mode?

And all runs with normal mode on should be rejected?

Yes. You just need to state in the rules that playing on speedrun mode is required. I did a similar thing in "Fireblob Winter", also a game by NoaDev that has a speedrun mode.

Huh, nice I saw someone try to get Gum Adventures DX gonna see if its added to sr.c

I will Delete normal mode from mini switcher and arrows

By the way, can you please add some rules to the game/category? I myself know what to do, of course, but having only "IGT" written doesn't really help.

Yeah ill do so
