IBA Gameplay: The Devil is in the Details
The IBA is based on a simple formula called the 'TENDEX' (sometimes
abbreviated and shown as 'TDX'). The TENDEX is a ratio computed from
eleven key statistical data points: 1) points scored, 2) assists, 3) steals,
4) rebounds, 5) blocks, 6) turnovers, 7) field goals attempted, 8) field
goals made, 9) free throws attempted, 10) free throws made, and 11) minutes
played. You would think that the name 'TENDEX' implies ten data
points... but 'ELEVENDEX' just didn't sound right. The player's number of
fouls is also considered but isn't used in the ratio itself; instead it is
used in the gameplay as an IBA game is played.
This will be described in detail below when IBA gameplay is discussed.
Here is the formula used to compute the TENDEX ratio:
pts + asst + steal + reb + blck - to - (fga - fgm) - (fta - ftm)
TENDEX = ------------------------------------------------------------------

You can review all of the season TENDEX ratings using the
show stats
utility (as previously noted, remember that sometimes TENDEX is
abbreviated to TDX). If you wish, you can mentally verify the computation
of a few season TENDEX ratings to get the hang of how the ratio is computed.
Now click on a player (e.g.
Shaquille Oneal) to review the season to season and the game by game
TENDEX ratings for that player. These player stats pages show personal
data, a scouting summary, year to year TENDEX trends, and game by game
TENDEX calculations. Probably the most important items on these personal
player pages are the game by game TENDEX calculations and the information
in the 'Scouting Summary' about the next NBA game in which the player will
participate. (Why? This will become clear as you read on).
