I know this isn't exactly what you asked, but there is a factor that might give you pause. There is a glitch in the way runs are sorted if you submit two runs in the same category that were completed on the same date; there is a variable for the the run's time of day but this point of data is set for all runs to the same default time of day, and this means the sort order gets mixed up. It's not a big deal if you do submit multiple PBs that were run in a single day--as long as the mods are happy to have the activity--it just looks weird on your profile if you look closely. If that bothers you, you could limit your submissions to one pb per day of running. Unless that's been fixed.
Somebody reported there is actually some sort of delay, not sure how or why or if it's just a glitch...
@dha That's been here since I joined the site in August. I got that message when I first tried to submit several IL runs in quick succession. It probably got added to prevent spammers from flooding a leaderboard.
I'd guess it doesn't apply to moderators for a game, in which case it often wouldn't apply to you.
