What's your total play-time?

For every day I play I made: around 822,320 exp
For every hour I played I made: around 34,262 exp
For every minute I played I made: around 571 exp
for every second I played I made: around 9.5exp

So if I play 500 more days I'll have a total of (410,400,000+131,020,332)= around 541,420,332 exp

Edit: How many years would it take me to complete runescape
"99 in every skill + dung"

I've played around 6 years, my total exp/6 = 21,836,722 exp per year 24x"around 13m)= 312,000,000+(dung)120000000=
432,000,000-my current total exp= 300,979,668/21,836,722= 13.78

It will take me around 14 years to finish runescape not counting jagex adding a skill every now and then
