Due to the nature of how different loads are for this game from PS2 on disc, PS2 on HDD, PS3, and emulation... it is best to manually remove loads via video editing and provide a final time that way. I have been doing this for several other games and have experience doing so.
Loads in this game are all fully blank frames and frames that include the bottom right text, "Now Loading..."
In addition it is best to cut the time in GP races between when the player crosses the finish line and when 6th place crosses the finish line (unless the player is 6th or worse) in order to remove arbitrary time that would eliminate gains from completing races quickly.
While I do not always upload the loadless edits by default I do keep them all and can certainly provide them upon request.
