99 defence on double exp weekend?

Is it possible to get 99 defence on double exp weekend starting at level 60 defence?
If so how and where should I train?

 

No.

You normally get around 100k defense exp per hour at armored zombies, more or less. In close to max gear with pots. You would need 12.5M exp which is impossible to attain in such a short period of time. BXP weekend only lasts for 10 hours (Right?). And the rate goes down every 30 minutes. You could be earning 300k defense exp per hour in the first 30 minutes, but half of that in the 3rd or so hour.

You would need to spend a total of around 100 hours, double exp lasts 10 hours, and you don't get x2 exp the whole time.

This is assuming that you're maxed strength, with good gear, and decent attack. Rates would be much lower if otherwise.

 

Aw! That sucks lol but thanks.
I'm only 61 combat with 51 Attack. 51 strenght. 60 defense. So my 99 plan not happening no time soon lol.
