How Safe Is a Lead?
Your team scores first and leads after the opening period. Do you relax, or is a hockey game too long for one goal to mean much yet?
Lead safety
Across every finished regular-season game league-wide, somebody is out in front after the 1st period 75% of the time. The rest are tied. When a leader does exist that early, they go on to win the game 80.3% of the time. That's a strong hold rate for a period this early. Two periods remain, and the team in front is already the clear favorite.
So does the picture change once the 2nd intermission rolls around, with only twenty minutes left instead of forty? It changes a lot. The hold rate jumps 8.5 points, from 80.3% to 88.8%. A 1st-period lead is a lean; a 2nd-period lead is a genuine signal, because there's less time left for it to disappear.
Tie watch
If leads aren't automatic, the flip side is worth asking too: how often does neither team ever pull away at all? The model has its own opinion on how often games should end level. The question is whether that opinion matches reality.
The two numbers land close together: 10.8% predicted against 10.5% observed. That's about as calibrated as a draw forecast gets. When the model says a game is draw-prone, the league backs it up. So when a specific game's predicted draw chance clears 16.7%, that's not noise. It's the model flagging a genuinely stalemate-shaped matchup, which is exactly why the site calls it out.
