Indeed. We'll see if they make any changes in the remaster if it ends up happening, and you might get your wish then.
I sure would hate to lose a run because I happened to charge into a fool at the same time he is becoming big.
When are we going to have IL 100% for all levels? Start timing on initial landing? I can understand the flight levels have an in game timer, but don't see why the other levels can't be added?
If there was some sort of function in the remaster where it had an ingame time next to each level in the inventory saying how long you spent (like Banjo-Kazooie) then sure I'd play around with it, but since it'd be RTA timed I wouldn't compete myself. 120% is fairly short for a 100% spyro category and I'm fine just seeing a best segment and knowing I did well. They tried implementing a similar idea in Crash 2 IL leaderboard but it didn't take off and it turned out to be more effort that it was worth. If you'd like to do it yourself, there's nothing stopping you, but I would be shocked if it was added to speedrun.com considering IL flight times are already present.
I appreciate your suggestion Jonny but at this time we will not be adding Individual Level leaderboards for non-flight levels.
