About the Skilling Tables

October 31, 2013

The skilling tables will be used to provide the skill guides with accurate information. This began as a way to confirm the items obtained when pickpocketing, but soon expanded to include the skills: Thieving, Mining and Fishing. Below is an example of pickpocketing one of the monsters.

The Rogue(21) page was the first thieving page created.

thieving table

Thieving Table: A listing of each theft. If the theft column is blank then the theft generated more than one type of item. If the name of an item is in red, then that is the last item for a given run.


Summary: This shows the total number of thefts, the total number of items acquired from all the thefts, how many of the thefts acquired multiple items and the item rate for multiple items acquired. Also shown is the criteria that I use to determine if something is a common item, uncommon item, rare item, very rare item or an extremely rare item. These rates are adjusted as more information is obtained.


An item with a 1 in 2.5 ( 40 % ) item rate indicates that the odds favor 1 of that item on average being acquired in 3 thefts. If the common item rate is set at less than 20, then this item is considered a common item.

An item with a 1 in 56.4 ( 1.77 % ) with the uncommon item rate set to greater than or equal to 20 and less than 100 would be considered uncommon.

Multiple Item Note:

A multiple item is where more than one item is thieved and the combination is random. This is different than a theft that contains a single item in a quantity of more than one as with coins or runes. Also a theft is single if there are different items but the combination is not random as with, a big bone and two normal bones, that are always acquired together.

item rate table

Item Rate Table: This table lists the type of items acquired both common (as with herbs, runes and gems) and individual, the number of times the item was acquired and the rate they were acquired at ( 1 in ) relative to the total number of thefts. When multiple numbers of an item are acquired, such as with coins (the quantity follows the name in parentheses), then the individual item rates are also listed.

thieving data base information

Thieving Data Base Information: This table lists the types of unique items acquired and shows the various quantities acquired of that item.

herb item rate table

Herb Item Rate Table: The number of multiple herbs acquired (2 or more per theft) is shown and the item rate for multiple herbs. The table above lists the item rate of a specific herb when a herb is acquired as well as the item rate for any given theft.

rune item rate table

Rune Item Rate Table: The table above lists the item rate of a specific rune when a rune is acquired as well as the total number of runes acquired for all the runs.

gem item rate table

Gem Item Rate Table: The table above lists the item rate of a specific gem when a gem is acquired as well as the item rate for any given theft.

run data

Run Data: This shows the number of runs from the bank to the target if my inventory gets full, the average number of thefts per run, the average number of items per run, the total number of coins acquired, the average number of coins per theft and the average number of coins acquired per run. The minimum and maximum thefts and items over the recorded runs.

The table above shows information about each run. The number of thefts, the theft number of the last item, the number of items, the item number of the last item and the number of times a selected item event occurred. The total number of the selected item event that occurred for all the runs is shown below the item event pop-up menu.

data graphing

Graph Item: This section allows you to choose what items or groups of items to graph. The check buttons are used to select/unselect the various items or groups of items. When items are acquired in various amounts, then a group button is added as a selection choice such as with the Coins, Gem, Herb or Rune checkboxes. The color of the checkbox is the color of the marker for that item on the graph.

The buttons above the checkboxes function as follows:

Clear All:Uncheck all the checkboxes.
Set All:Check all the checkboxes.
Erase:Erases the graph.
Redraw:Redraws the graph.

Graph Item Data: The graph shows at what item number a given item occurs. The x axis is 1 pixel per item. The vertical height is for visibility. Below the item number labels is a two color bar, that shows which items belong to a run. Below each bar color is the run number.

Graph Status: If the JavaScript code detects a problem with the graphics, it will display a message in this area. Currently if the browser doesn't support the Canvas API or the Canvas Text API a message will appear.

Notes: If this section is present, it will contain information about the theft table data.
