Summary of "3.1. Time on Ice (TOI)"

Understanding Time on Ice (TOI) in Hockey

The video explains the concept and tracking of Time on Ice (TOI) in hockey, detailing how to accurately record player shifts and line changes during a game.

What is TOI?

TOI measures how long each player spends on the ice.
A strict one-in, one-out substitution rule is followed to maintain the correct number of players on the ice.

Standard Lineups

Five-on-five play:
- 3 forwards
- 2 defensemen
- 1 goalie
Power plays:
- 4 forwards
- 1 defenseman
Penalty kills:
- Use fewer skaters than standard

Special situations such as delayed penalties and empty nets affect player counts and TOI tracking.

Importance of Precise Timing

Plus-minus statistics depend on knowing exactly who was on the ice at the moment a goal is scored.
When players celebrate goals, only those clearly involved or on the ice longer should be counted.

Tracking TOI

TOI can be tracked by selecting entire lines (forwards or defense) or by manually adding individual players.
Players typically rotate about every minute.
Substitutions can be delayed by events like icing, which forces players to stay on the ice for the next faceoff.
Full line changes often occur when a player goes behind the net holding the puck.

Logging Player Changes

Carefully observe who enters and leaves the ice.
Ensure forwards swap with forwards and defensemen with defensemen.
If a player is mistakenly logged who never entered, delete that entry and add the correct player at the same time.
During stoppages or interruptions, player changes must be logged before the puck drop to maintain accuracy.

Additional Notes on TOI Tracking

Players on ice for over two minutes are flagged in red as a warning, not an error.
After substitutions, allow the system to update rather than clicking repeatedly.
At the start of each period, confirm the game clock reads 20:00 to avoid mislogging player times in the wrong period.
At the end of each period, manually log all players off the ice, including goalies, to maintain correct records.
