When I submitted my 18.40 on MMF a few months ago, I entered the time as 18 seconds because there were no option to add milliseconds. Once I lowered the time to an 18.22, I submitted that and the 18.22 was marked as obsolete even though it was 0.18 seconds faster. I would highly appreciate it if the mods allowed for more accurate time submissions (H:MM:SS.msmsms)
