There is already such a thing. It's under the "Level Leaderboard" tab on this current page. I'm assuming you are potentially using a mobile version or other version of speedrun.com and it isn't showing for you. Here's a link to the Clean House leaderboards that you suggested https://www.speedrun.com/mw2019/Clean_House If you have any other questions related to speedrunning and COD feel free to join the discord. There's a link on this page which should send you an invite. Plenty of heads in there to help you with anything and everything cod.

If it's splits you are looking for they are written below some of the records if you want to compare them. Note that autosplitter doesn't work mw19 and you have to split yourself. If you have any questions or i didn't answer yours, you can also join the COD Discord. Many way more knowledgeable people on there about livesplit and other COD speedrunning related stuff.

Was wondering if using the 0 star skip straight to wingcap stage be allowed in 30 star category. Might run it when i have free time in the next little bit and am curious. Climbing the tower from snowy mountains to wingcap stage takes between 23-26 seconds whereas using the 0 star skip it takes about 13-16 seconds to reach wingcap stage. The route would simply have the 0 star skip(wingcap stage) first thing in the run. Thanks in advance.
