Bones Exp Weekend Calculations???

So im training herblore for bxpw, so i did some calculations and this is what i got, although it seems like too much xp

I will make 5000 super attack pots.
I will try to average at least 1300 per hour (too much?)
This means that the multiplyer will go down 7 times (every half an hour)

So a maximum of 270 xp per pot and hopefully a minumum of 210 xp per pot.

Taking all this into account, i should be able to get : 2,184,000 xp (2.2m rounded up)

That seems an aweful lot of experience for just 5k potions, am i wrong?

7 Multiplyers : (assuming the multiplier reduces every 30 minutes)

2.7:351,000
2.6:338,000
2.5:325,000
2.4:312,000
2.3:299,000
2.2:286,000
2.1:273,000

These were my calculations:

Normal xp * Current multiplier = xp per pot.

xp per pot * 1300 (target made per hour)

Dont worry, the almighty Alex HC found my mistake,

Total experience gained is now around the 1.1m mark

Meron is the pro for maths

Here's your mistake
You can't make 1.3k potions in just 30 minutes Or can you?
