For example in this problem https://www.spoj.com/ranks/INVDIV/start=40 it shows 5.83s as my best submission
whereas if I go to my status page I can clearly see a successful submission with lower timing.
5.76s
The page doesn’t always update immediately. I’ve found that once there is an entry, it seems slow to update it if you improve your time. However, if you wait a while, it does update eventually.
