For co-op runs, players would have different loading times due to different hardwares. When it come to the loading time subtraction, which player's time should be used? The last one loaded into the game, the host, or the recording player?

If a player has a very slow pc and he is recording, others will always have enough time for weapon and marine adjustment. It is the same for the host. That is to say. A team Could use hardware strategy (or cpu usage strategy) to ensure all other players have plenty of time to change weapons.

Since the devs is preparing to add auto-ready settings into advanced setting menu. And auto-ready is widely accepted by dedicated servers And game community. My suggestion is to revise rule to specify the loading time for co-op. Suggested revisions are:
1. Please enable auto-ready via console, type "rd_ready_mark_override 1".(this will ensure the last loaded player is ready immediately)
2. Loading time starts at the first frame of loading screen appears, and ends on the first frame of last loaded player's ready mark appears.
3. All players are not allowed to change marine, weapons or equipment until the last player loaded into the game (i.e. ready mark appears). This can be verified by observing the menu animation and ready mark. Use lobby 8 players mod to guarantee this rule.

Hey, this is a great suggestion.

It will be added to the rules as soon as possible.
