Is it to do with the RNG dependence of the game?

It would be really useful for gadging my speed compared to what is needed for wr.

I can only speak for myself; I've simply been too lazy to get some IL's since you have to really grind to get an excellent time.

I know there was a thread that Zecora made asking for footage of IL's so that he can splice a "perfect run" together.

I've also got a segmented spreadsheet in the forums showing what really fast times are

True, So are they they IL times and upload if they are beaten?

Well someone might need to grind their Geon IL because I just beat it in a few frames and now I'm happy. I will post it but I have to edit out the 19 minutes of failed attempts to get it!
