I am going to update the OP with some more useful content on how to use Rawr. Part of it is going to be explain for the calculations work, to let people better interpret the results. Please let me know if you have any feedback on areas for improvement,. It does the following in order.
- Computes your stats from your current gear, including averages value of procs assuming you can cast a spell every 1.5 seconds.
- Computes how big your mana pool is given the fight parameters, this includes almost all mana related effects besides Illumination.
- Computes the average amount healing, mana costs, etc that each cast of HL/FoL/HS does.
- Computes time/mana spent on keeping up BoL, JotP, and SS.
- Computes how much time/mana/healing done by HS based on the options set.
- If Infusion of Light modeling is on, it calculates how many IoL procs you will get on average, then calculates how much mana used/healing done by the FoL/HL cast with IoL (ratio of the two is set by the user)
- Calculates the mana cost of HL during Divine Illumination. Computes how much time/mana/healing done is used assuming you spam Holy Light during Divine Illumination.
- With the remaining remaining mana that is not used by any of the previous steps it calculates how much time is spent on casting FoL and how much on HL presuming you use exactly all of your mana. It uses the following formula hl_time = (remainingMana - (remainingTime * fol_mps)) / (hl_mps - fol_mps)
- Tallies up all the healing done by the previous steps, computes the value GoHL heal, BoL heal, SS and absorbs.
- Adds it all up to determine the total amount of fight healing.
- Computes the average time in between casts.
- Repeats the whole thing 5 more times, but for the first step it estimates proc values using the average cast time calculated in step 11.
It doesn't computer the mana return of Illumination outright, rather It uses the following formula to determine the average cost of the heal.
((BaseMana * (DivineIllumination ? 0.5 : 1) - CostReduction) * (AbilityCostMultiplier - (GlyphOfSealOfWisdom ? .05f : 0f))) - BaseMana * .12 * PointsInIllumination * ChanceToCrit[/pre]
