TWIRP Composite Indexes TWIRP Skill Indexes

NOTE: After four months of doing TWIRP, I have discovered that the player profiles don’t really seem to differ much at all from the skill and combat composite indexes. As such, I have decided to stop providing them in my weekly reports. I am continuing to calculate the player profile indexes, however, in case they become relevant in the future.

The idea behind the TWIRP player profiles is to create indexes that represent how changes in item prices affect different styles of play within RuneScape. Obviously every player is unique and chooses a different blend of possible activities, but I felt that creating at least a few "stereotypical" profiles would show rather clearly how differently some players are affected by the same price changes.

Each player profile is constructed by weighting the value of subordinate indexes, taking into account the inputs and outputs appropriate to that player type. This includes, where appropriate, skill costs and production values, combat equipment and supply costs, monster drops, specialty item costs, minigame output and more.

There are currently four player profiles defined:

• Pure Skiller Profile Yield (TWIRP-P-SKILy): This profile is meant to represent the typical "pure skiller" RuneScape player—someone who shuns combat in favor of peaceful skills and occupations. As such, the profile depends heavily on the Skill Composite indexes, mostly reflecting the relative changes in skill costs and value produced. Also included here is a small weighting for non-combat minigames, as well as discontinued and luxury item costs.
  
  
• PvM Profile Yield (TWIRP-P-PVMy): The opposite of the skiller profile, this profile is based only on combat indexes, including the Slayer and Prayer skills. Again here, there is a small weighting for minigames, this time combat-related ones—including Treasure Trails, since clue scrolls are mainly obtained via combat—as well as discontinued and luxury items.
  
  
• PvP Profile Affordability (TWIRP-P-PVPa): This is the only affordability profile (as opposed to yield) because PvP is essentially "input only". That's not that you can't get anything out of any PvP activities, but in many you get nothing tangible (Castle Wars), and in most others it's unreliable and pretty much impossible to measure. Thus, this index only measures how affordable PvP combat is becoming.
  
  
• Balanced Profile Yield (TWIRP-P-BALy): This profile is an attempt to put together an index representing the typical example of an "average RuneScape player". This means it takes into account all of the various inputs and outputs of the game: combat costs, combat drops, non-combat skill inputs and outputs, minigames and so forth.

I may add more player profiles in the future.

I should also note that PvP combat affordability is not just the "affordability half" of the PvM Profile Yield Index. In other words, I did not assume that the costs of PvM combat were the same as those of PvP combat; for one thing, the split in combat styles is very different for PvP (much more emphasis on ranging, and especially combat magic, than is found among players fighting monsters).
