So 2 questions regarding the bonus xp weekend. First how many pouches can I make per 10 minutes using kyatt and duelling rings? Second what is the XP multiplier at each 10 minute interval for the first 2-3 hours? I plan to be using this to roughly calculate what order I should use my charms and what pouches to make to maximize my end level.

For the second question, use this: http://www.wolframalpha.com/input/?i=%28integrate+%28%28%28x-10%29%2F7.5%29^2%2B1.1%29+dx+from+a+to+b%29+divide+by+%28b-a%29

 

Substitute values for a and b (in hours), where a is your start time and b is your end time.

 

The value obtained is the average multiplier for the time period.

For the second question, use this: http://www.wolframalpha.com/input/?i=%28integrate+%28%28%28x-10%29%2F7.5%29^2%2B1.1%29+dx+from+a+to+b%29+divide+by+%28b-a%29

 

Substitute values for a and b (in hours), where a is your start time and b is your end time.

 

The value obtained is the average multiplier for the time period.

I checked for first 10 minutes and then next 10 minutes and they both gave numbers over 2.7 which is what Jagex said it would start at.

2.7 is the approximate average multiplier for the 1st hour.

 

If you use the formula

and substitute Hours logged in = 0, clearly it starts at 259/90 > 2.7.

 

Also, the graph clearly starts at somewhere above 2.7.

When you initially log in on the weekend, you will gain approx 2.7x XP for all "normal training" activities (see the question below for a list). While you are logged in, a timer will be running over the time you are logged into the game. Over time, the bonus will decrease to a minimum of 1.1x your usual rate.

Approximately.

 

The formula given shows that in the first second you should get about 2.87x xp.

Thanks, I just didn't expect Jagex to be off by so much even with approximately. I found the number 3000 pouches per hour, is that about right?

3k is the top end. Closer to 2.5k if you don't pay masses of attention.
