Effective Experience or eXP describes the amount of experience points a player is able to accumulate within a period of time (usually 1 hour) while taking the value of a players time into account. Effective Experience rates can be used to compare various training methods that differ in both GP/h and XP/h.

Formulas[edit | edit source]

The following formula can be used to calculate a training methods eXP/h.

  • eXP/h = (skill-XP/h) / (((skill-GP/h) / ((max-GP/h) * -1)) +1)

To calculate the GP/h a player has to make in order for the eXP/h values of two skills be equal the following formula can be used.

  • max-GP/h = (((GP/h Skill 1) * (GP/h Skill 2)) - ((XP/h Skill 1) * (XP/h Skill 2))) / ((XP/h Skill 1) - (XP/h Skill 2))

Examples[edit | edit source]

Note: the values of items and profits used in this example are not accurate or based on GE values.

Bob has to decide between the two following two training methods:

With the best money making method known to Bob he values his time at 500k GP/h.

Green d'hide bodies[edit | edit source]

If bob were to craft Green d'hide bodies for 1 hour it would then take him 6,5 hours to cover the lost amount of coins because:

  • (GP/h) / ((max-GP/h) * -1) = (-3250k / 500k) * -1 = 6.5 hours

So in order to gain 306k XP/h though D'Hide Bodies bob would have to effectively spend 7.5 hours of his time. 6.5 hours to raise enough coins followed by 1 hour to craft the armour.

This would result in the following eXP/h:

  • 306k / 7.5 = 40.8k eXP/h
  • (skill-XP/h) / (((skill-GP/h) / ((max-GP/h) * -1)) +1) = (306k) / (((-3250k) / ((500k) * -1)) +1) = 40.8k eXP/h

Emerald rings[edit | edit source]

If Bob were to craft Emerald Rings for 1 hour then this would save him 12 minutes of his time because:

  • (GP/h) / ((max-GP/h) * -1) = (100k / 500k) * -1) = -0.2 hours = -12 minutes

So in order to gain 63k XP/h though Emerald Rings bob would have to effectively spend 48 minutes of his time. 1 hour to craft the armour followed by -12 minutes saved on raising coins.

This would result in the following eXP/h:

  • 63k / 0.8 = 78.8k eXP/h
  • (skill-XP/h) / (((skill-GP/h) / ((max-GP/h) * -1)) +1) = (63k) / (((100k) / ((500k) * -1)) +1) = 78.8k eXP

Calculating the equilibrium[edit | edit source]

Bob now wants to know: "So much GP/h do I have to make before I'm better off making Green D'Hide Bodies?".

Bob can deduct this answer by solving the following equation.

  • (skill-1-XP/h) / (((skill-1-GP/h) / ((max-GP/h) * -1)) +1) = (skill-2-XP/h) / (((skill-2-GP/h) / ((max-GP/h) * -1)) +1)
  • ((skill-1-GP/h * skill-2-GP/h) - (skill1-XP/h * skill2-XP/h)) / (skill1-XP/h - skill2-XP/h) = max-GP/h
  • ((100k * -3250k) - (63k * 306k)) / (63k - 306k) = 1417k

If Bob values his time at exactly 1417k GP/h then the eXP/h from making Emerald Rings or Green D'hide Bodies would be equal. If Bob makes over 1417k GP/h the eXP/h from Green D'hide Bodies will be higher than the eXP/h from Emerald Rings and vice versa.
