This day`n`age, it`d be the trickiest thing to do.
In all honesty I see this SuperPI record in the OP with a `so what?` attitude. Yeah it`s a milestone. If it was a really large jump to like 5s or something, it might`ve opened my eyes, but I`m sure I`ve seen hundreds of people do 7.03 or similar. And to be overly critical, an average over 10 runs would grab my attention even more.
1 off runs of SuperPI can sway quite a bit, the key is to watch the first output it gives u, or how many times it repeats the same second. Stop it and run it again if it doesn`t look favorable.
